How do you work out the midpoint of a line on a co-ordinate grid?
Paramorechick
The x-coordinate of the midpoint is the average of the x-coordinates of the end-points of the line and the y-coordinate of the midpoint is the average of the y-coordinates of the end-points of the line.

What is the slope of the line passin' through 1 2?
Another coordinate is needed to work out the slope.
How do you do a multiplication grid with missing numbers?
Well you have to answer all the questions you can and then you have to look at all the answers you have and use them to work out the rest you have to look at the answers you have and work out what the other number is to work out all the numbers on the outside of the grid! Hope I have helped you for tests and homework from now on! Ed R
What is the equation and its perpendicular distance from the point -3 -5 whose line meets the line of 0 5 to 3 0 at its midpoint on the Cartesian plane showing work?
Points: (0, 5) and (3, 0) Midpoint: (1.5, 2.5) Slope: -5/3 Perpendicular slope: 3/5 Perpendicular equation: y--5 = 3/5(x--3) => 5y = 3x-16 Distance is the square root of (1.5--3)^2+(2.5--5)^2 = 8.746 to three decimal places
What do you call the point at which two lines intersect?
where the two lines cross is called their point of intersectionHere we will cover a method for finding the point of intersection for two linear functions. That is, we will find the (x, y) coordinate pair for the point were two lines cross.Our example will use these two functions:f(x) = 2x + 3g(x) = -0.5x + 7We will call the first one Line 1, and the second Line 2. Since we will be graphing these functions on the x, y coordinate axes, we can express the lines this way:y = 2x + 3y = -0.5x + 7Those two lines look this way:Now, where the two lines cross is called their point of intersection. Certainly this point has (x, y) coordinates. It is the same point for Line 1 and for Line 2. So, at the point of intersection the (x, y) coordinates for Line 1 equal the (x, y) coordinates for Line 2.Since at the point of intersection the two y-coordinates are equal, (we'll get to the x-coordinates in a moment), let's set the y-coordinate from Line 1 equal to the y-coordinate from Line 2.The y-coordinate for Line 1 is calculated this way:y = 2x + 3The y-coordinate for Line 2 is calculated this way:y = -0.5x + 7Setting the two y-coordinates equal looks like this:2x + 3 = -0.5x + 7Now, we do some algebra to find the x-coordinate at the point of intersection: 2x + 3 = -0.5x + 7We start here.2.5x + 3 = 7Add 0.5x to each side.2.5x = 4Subtract 3 from each side.x = 4/2.5Divide each side by 2.5.x = 1.6Divide 4 by 2.5.So, we have the x-coordinate for the point of intersection. It's x = 1.6. Now, let's find the y-coordinate. The y-coordinate can be found by placing the x-coordinate, 1.6, into either of the equations for the lines and solving for y. We will first use the equation for Line 1:y = 2x + 3y =2(1.6) + 3y = 3.2 + 3y = 6.2Therefore, the y-coordinate is 6.2. To make sure our calculations are correct, and also to demonstrate a point, we should get the same y-coordinate if we use the equation for Line 2. Let's try that:y = -0.5x + 7y = -0.5(1.6) + 7y = -0.8 + 7y = 6.2Well, looks like everything has worked out. The point of intersection for these two lines is (1.6, 6.2). If you look back at the graph, this certainly makes sense:Here's the summary of our methods:Get the two equations for the lines into slope-intercept form. That is, have them in this form: y = mx + b.Set the two equations for y equal to each other.Solve for x. This will be the x-coordinate for the point of intersection.Use this x-coordinate and plug it into either of the original equations for the lines and solve for y. This will be the y-coordinate of the point of intersection.As a check for your work plug the x-coordinate into the other equation and you should get the same y-coordinate.You now have the x-coordinate and y-coordinate for the point of intersection.Actually, there is nothing special about the functions being linear functions. This method could be used to find the point or points of intersection between many other types of functions. One would express the functions in 'y =' form, set the right side of these forms equal to each other, solve for x, (or x's), and use this x, (or x's), to find the corresponding y, (or y's).Here's a calculator to help you check your work. Make up two linear functions in slope-intercept form. Calculate the point of intersection using the above methods. Then enter the slope and y-intercept for each line into the calculator and click the button to check your work.
How do you work out midpoint coordinates?
The 'x' coordinate of the midpoint is the average of the 'x' coordinatesof the end points.The 'y' coordinate of the midpoint is the average of the 'y' coordinatesof the end points.Note:In order to use this handy factoid, you'll need to know how to find the averageof two numbers.
What methods could you use to calculate the x-coordinate of the midpoint of a horizontal segment with the endpoints of -6 0 and 6 0?
You can calculate the x coordinate of the midpoint by: calculating the average of the x coordinates, which would be the average of the endpoints. You could also count by hand, but if you are doing schoolwork there would be no work to show.

What is the slope of the line passin' through 1 2?
Another coordinate is needed to work out the slope.
How do you work out a coordinate when there are no numbers on the x and y axis?
To work out a coordinate when there are no numbers on either the X or Y axis begin by drawing a vertical line down from the point of interest and have it cross the horizontal axis. Where the two meet label it as X and then use a ruler to measure from the 0 point to the X. This will give you the X axis coordinate. Repeat the process to find the Y coordinate but draw a horizontal line from the point of interest instead of a vertical line.
What is the equation of a line in the slope is -7 through -65?
To work out the equation of a straight line the slope and an (x, y) coordinate must be given
Can you use dragon naturally speaking on dual monitors?
You can but the Mouse Grid function doesn't work on the second monitor as of version 12. You can use the mouse move functions and call windows but pointing the mouse to a specific coordinate on the second monitor doesn't work because the mouse grid only goes from 1-9 and that is on the fist monitor.
What is the perpendicular equation that meets the line of 2 3 and 5 7 at its midpoint showing key aspects of work?
Here are the key steps:* Find the midpoint of the given line. * Find the slope of the given line. * Divide -1 (minus one) by this slope, to get the slope of the perpendicular line. * Write an equation for a line that goes through the given point, and that has the given slope.
Does the national grid transmit at high voltage or a high current?
Both. That way a lot of power can be transmitted. The largest UK grid circuits work at 400 kV and a line of pylons can transmit up to 6000 MVA.
Formula to find if lines are straight?
Hola, The equation of a straight line is y = mx + c , where y is y-coordinate, x is x-coordinate, m is the gradient, and c is where the line passes the y axis. m = y2 - y1 / x2 - x1 choose two points on your line and work out m, then see if another point on the line fits the first formula
