Answer:
0
Step-by-step explanation:
You first multiply -2(-2) which will be 4 since a negative times a negative is a positive. Next you subtract 4 and -4 which is 0. Lastly you bring down the y which is equal to 0.
Just substitute it into the gradient formula which is: y2 - y1 / x2 - x1. So 2-3/2-9 = -1/-7 = 1/7
