Question:

How do you graph a linear equation (y=mx+b)?

Raymond M.

Start from the coordinate (0,0) and go up or down the y axis depending on the the b has a + or — number which is your y-intercept. Next you would plot your slope. For example, if it was 3/4x you would move up 3 and 4 right. However, if the slope had a minus you would do the opposite.
