Step-by-step explanation:
The answer is A. (x - 4)(x - 12).
Here are the pictures of the steps I took when solving it as well as the answer to what X is
So you will use slope formula which is m = (y2 -- y1) / (x2 -- x1)
-1 minus -7=6
13 minus -8=21
Remember it changes to a positive Keep,Change,Change
So its 6/21
Or 1/4

:)
The slope is 2 because remember, y= mx+b
m= slope
the slope is always multiplied by x
