The slope would be 3x and the y-intercept would be 0.

Explanation:

1)Slope intercept form is y=mx+b.

2)Your form is also in y=mx+b but is simply
missing the b portion of it. So your equation is y=mx
m=slope. x=x-intercept.

3)You would begin by graphing the y-intercept, which in this case is 0. Graph the point at (0,0)

4)Because the slope is positive, you would have a line that slants to the right. Slope is rise/run and 3x is the same thing as 3/1.

5)Go up three units and over one unit (making sure you are going to the right of the (0,0) point.

6)Continue to graph, following the pattern, 3 up, 1 over, plotting the points as you go.
