Question 130314: how would you graph y=3x?
Answer by ilana(307)   (Show Source):
You can put this solution on YOUR website! This is a linear equation in slope-intercept form, y=mx+b, where m is the slope and b is the y-intercept. Here, m=3 and b=0. To graph a line in this form, start on the y-axis at the y-intercept. Here that means to start by making a point at (0,0). Since the slope is 3, and slope is rise/run, this line will go up 3 units every time it goes to the right 1 unit. So after (0,0) you will go to (1,3) and make another point. Now connect (0,0) and (1,3) and continue the line in both directions with a ruler (or plot more points first if you want). Most teachers also like for you to draw arrows on both ends of the line to show that that line can go on forever.
