How do you graph y = -x?

So as Bob said, it is go down from left to right at 45 degrees and through origin. Those numbers should on the y=-x this graph line. For instance, (-1,1). Since x=-1, as equation shows, y should be 1. You could list those (x,y) , randomly x or y and use equition to calculate other one you dont know ,in order to find points and connect them. Ps: you only need make two (x,y)and then you can graph it . OR you could use most western way to solve it. Find 'slove' and graph it . I don't recommend this way but it is your choice. Good luck:)

The question is "how do I graph"--------If you are using a computer program to graph like excel you put your x values in one column and the corresponding y values in the next column. Then go to the x-y plot button, select your data and click on plot. What you will see is the same as what you would get if you drew your own set of x-y axes and plotted your data. So draw and x-y set of axes just roughly on a piece of blank paper----x runs horizontally and runs say from -10 to +10 and the y axis is verticle and intersects the x axis at zero. Make the y axis the same length from -10 to + 10. Plot your points on this graph. When x is zero so is y zero so your first point is at the intersection of the x-y axes called 0,0. Plot the other points-----x+2 and y=-2 also written 2, -2 etc and draw the straight line thru the points.

It's a straight line going downwards left to right at 45 degrees, going through the origin.
