See "ANOTHER IDEA", below.

Point-Slope Equation Form might be easiest to use.

y-y=m%28x-%28-3%29%29
0=%28%282-y%29%2F%28x%2B3%29%29%28x%2B3%29
0=2-y
y=2?

Try slope-intercept form instead.
m=%282-y%29%2F%28x%2B3%29
y=mx+b
b=y-mx
b=y-%28%282-y%29%2F%28x%2B3%29%29%28-3%29
-
y=%28%282-y%29%2F%28x%2B3%29%29x%2B%28y-%28%282-y%29%2F%28x%2B3%29%29%28-3%29%29
This will not be a line; NOT be a line!!

What you do with the two given points depends on what kind of equation and graph shape you expect, and maybe more than just those two ordered pairs.


Another idea:
Each of your given points represents a line ---- EACH of the given points.
(-3,y) is the line x=-3. All real values for y are included.
(x,2) is the line y=2. All real values for x are included.
These are two separate lines.
