Question

Help!
Find the linear equation by graphing:

y=x
y=-2x

Answer 1

Let's graph these one by one

Answer 2

First start out with a blank xy axis

Answer 3

Then add on tick marks to label the axis

Answer 4

The equation y=x is really y=1x+0

so the slope is 1, the y-intercept is 0

This means you plot the point (0,0). Then you go up 1, over to the right 1 unit, to get to (1,1)



That is the graph of y = x
