How do you graph a line using slope intercept form of a linear equation?
you create ordered pairs or a serious of (x,y) points on the graph which you can plot and connect with a straight line
How do you solve this simultaneous equation 2y equals 12-x and 3y equals x-2 by using a graph?
Plot the straight line representing 2y = 12 - x. Plot the straight line representing 3y = x - 2 The coordinates of the point of intersection of these two lines is the solution to the simultaneous equations.
How do you graph the equation y equals -x-3?
Here is a simple way to graph a linear equation. A linear equation is one that has a y term (a number times y), an x term and a constant (but no squares or cubes or square roots etc.): Let x = 0 and use the equation to find y. This gives you one point on the graph: (0, -3) Let y = 0 and use the equation to find x. This gives you another point on the graph (3, 0) Plot these two points, join them with a line and extend in both directions. However, this method gives only one point if the equation is of the form y = ax where a is some non-zero constant; and that point is (0,0) In that case, use (1,a) as the second point.
How do you find the equation for the line of best fit?
There are many ways, but probably you aren't in a statistics class, but in an algebra class. Step 1 plot all the data points on a coordinate plane graph (x-y graph) Step 2 estimate a line 'close' to points. Step 3 use 2 points ON THE LINE (these do not need to be data points) Step 4 find slope of line using points from step 3 Step 5 use point-slope formula to write the equation.
How can you show that two objects are proportional with an equation?
You can use a plot diagram to plot the points and if they all go straight through the origin then it is proportional
How do you solve 21x-7y equals 4?
You plot the equation as a graph. Every one of the infinitely many points on the graph is a solution.
When we plot all the points that satisfy an equation or inequality we do what to it?
Graph it (the equation).
When we plot all the points that satisfy an equation or inequality we it?
graph
When we plot all the points that satisfy an equation or inequality we?
graph
Why do you need to find the equation of a line?
So that you can plot out the points of a straight line on graph paper.
Graph the linear equation y equals 0.75x - 3?
-2.25
How do you graph when the equation is not slope intercept form?
To graph an equation that is not in slope-intercept form, you can use the process of finding points on the graph and plotting them. Choose a few x-values, plug them into the equation to find the corresponding y-values, and plot those points on the graph. Then, connect the points with a smooth line to complete the graph.
What's the difference between a line plot and a line graph?
A line plot is just a graph with points and a line graph the points are connected.
What is the definition of graph of an equation?
Plot the solution of the equation for various variables in the equation
How do you put 2x plus y equals 9 on a graph?
Solve for y; calculate a few sample points (plug in a value for x, then calculate the corresponding value for y); plot on the graph. Two points should be enough in theory (this equation is a straight line), but a third point helps you confirm that your calculations are correct.Solve for y; calculate a few sample points (plug in a value for x, then calculate the corresponding value for y); plot on the graph.

How do you graph the linear equation 3x plus y equals -4?
3x + y = -4 -3x -3x y = - 4 -3x now plug in points!+++To clarify the principle, re-arrange the equation so it reads as "y = [something done to x]" then calculate a table of points for the plot itself.
