Checking Choice A: y - 3 = 2(x-2)


Let's check the first point (-3,2)
So x = -3 and y = 2. Plug these values into the equation

y - 3 = 2(x-2)
2 - 3 = 2(-3-2)
-1 = 2(-5)
-1 = -10


The last equation -1 = -10 is false. So y - 3 = 2(x-2) is false when (x,y) = (-3,2). This means (-3,2) is NOT on the line y - 3 = 2(x-2)


So it's impossible for choice A to be the answer. We can eliminate choice A


Go through the other choices and check both points. Make sure that both points make the equation true. If not, then you can eliminate the answer choice like I did above.
