Question

What is the slope and intercept for `y=3x` and how would you graph it?

Answer 1

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.
