-3 is a fraction, the denominator is just 1.
Maybe thinking about it that way will help you.

So start with the y-intercept (0,2).
The slope is change in y divided by change in x.
So if I move 1 unit in x, I should move -3 units in y.
(0,2)+(1%7D%7D%5D%2C%7B%7B%7B-3)=(0%2B1,2-3)=(1,-1)
So then (1,-1) is another point on the line.
Plot those two points and connect them with the line.

Hi,
.
Note: All slopes can be thought of as being fractions. m = -3 or (-3/1) for ex
.
Question states the slope intercept form of the line is
y = -3x + 2
.
Pt(0,2) on the line. another would be Pt.(1,-1) As y decreases by 3, x increase by 1.
