Question 375157: I can't remember graphing at all and am attempting to help my daughter with her home work. Can you explain how to solve the following problem so that I may understand and explain to her?
x=3y
Thank you!

Answer by robertb(5830)   (Show Source):
You can put this solution on YOUR website! This is a linear equation. To graph a linear equation, you need two points on the line. If x = 0, then y = 0. (Just substitute x=0 into the eqution.) If x = 3, then 3 = 3y, or y = 1. Hence two points on the line are (0,0) and (3,1). Plot these two points on the line and try your best two draw a straight line through them.
