Place a dot on the origin.
A line that has a slope of [tex] \frac{-2}{3}[/tex] goes by this formula:
[tex] \frac{rise}{run} [/tex]
So "rise -2" and "run 3."
Rise -2 is basically go down 2, so go down 2 units from the origin. Run 3 means go right 3 units from (0, -2).
Draw a line through (3, -2) and (0, 0).
