Explain how to graph 2x plus y equals 4?
2x + y = 4 can also be written y = -2x + 4. There are many methods to graphing linear equations. Here is my favorite: because there is only one variable (x) raised to the first power (x1 even though we don't often write it this way), we know that the graph is a straight line. So we need only find two points that lie on the graph and draw the straight line that runs through (and beyond) them.So plug in two different values for x and see what y= at these values. For instance, when x = 0, y = -2(0) + 4 = 4. So plot the point (0, 4) on your two-dimensional coordinate plane.Another x value: when x = 1. Plug that into the equation y = -2(1) + 4 = 2. So the point (1, 2) should be on the graph. A straight line through these two points gives you the graph of the equation.*Another method is to find just one point on the graph, say (0, 4) as we did above, then use the slope (the m in y = mx + b form) to direct the rest of the line. Our slope is -2, so every time x increases by one (move one notch to the right), your y value will be two units less than the previous y value.
What is a minor diagonal matrix?
A minor diagonal matrix is one where the only non-zero entries are along the diagonal that runs from bottom most left to upper most right.
If a football player positioned on the scrimmage line runs straight downfield for 26 yards and then cuts to his left for 6.0 yards to receive a pass what is the football player's total displacement?
It is 26.68 yards, approx.
Which axis of a graph will always run vertically from bottom to top of the page?
The y-axis always runs vertically.
What makes a decreasing linear relationship a direct variation?
if the line runs through the origin it is a direct variation no matter if it is increasing or decreasing
Where is a horizontal line on a graph?
The one that runs left to right, you mean..
Which axis on a graph will always run horizontally left to right across the page?
On a standard Cartesian graph, there are two axes. The Y axis runs vertically, bottom to top and the X axis runs horizontally from left to right.
What is the slope of line x5?
5. if there is a line that says for instance y= 5x the answer on how to graph it would be the slope is the fraction. How far it "rises" on the graph, over how far it "runs" goes to the right or left. ( the answer is 5/1 or it rises 5 spaces on the graph and it goes to the right one) If a slope is negative it goes to the left. Also if it was y= 5x +3 it would do the same thing as before, but instead of starting from the origin (0,0) it would start at +3 and go from there.
What is the line that runs vertically on a bar graph called?
y-axis
What is a vertical line on a graph?
A vertical line is a line that runs up and down. On a graph, it is either the y axis or parallel to the y axis. It is also perpendicular to the x axis.
What is the horizontal scale that runs all the way from the left to right across the top of the table?
The horizontal scale is called the x-axis. It represents the independent variable in a graph or table, and it runs from left to right. It helps to show the relationship between the data points being plotted.
Why the horizontal axis of a graph runs?
The horizontal axis runs left to right because it is horizontal. The vertical axis runs up and down. In math, 'y' is associated with the horizontal axis and 'x' is associated with the vertical axis.
What is the graph line called that runs up and down?
vertical axis :)
What is the imaginary line on the globe that goes from left to right?
Latitude lines are the ones which are parallel to each other, with 0º being the Equator Longitude are the ones which radiate out from the poles and which get wider as they approach the Equator. 0º runs through Greenwich, near London.
What line type is quick and energetic?
A diagonal line that runs upwards and to the right.
Which planes runs longitudinally and divides the body into right and left planes?
The sagittal plane runs longitudinally and divides the body into right and left halves.
What is a set of elements that runs from left to right?
period
