y-3=\frac{-2}{-1-\left(-2\right)}\left(x-\left(-2\right)\right)
Subtract 3 from 1 to get -2.
y-3=\frac{-2}{-1+2}\left(x-\left(-2\right)\right)
The opposite of -2 is 2.
y-3=\frac{-2}{1}\left(x-\left(-2\right)\right)
Add -1 and 2 to get 1.
y-3=-2\left(x-\left(-2\right)\right)
Anything divided by one gives itself.
y-3=-2\left(x+2\right)
The opposite of -2 is 2.
y-3=-2x-4
Use the distributive property to multiply -2 by x+2.
-2x-4=y-3
Swap sides so that all variable terms are on the left hand side.
-2x=y-3+4
Add 4 to both sides.
-2x=y+1
