Answer:
Option D is correct.
Step-by-step explanation:
By looking at the graph attached, first look up the coordinates of the points A, C, D and G in order to find their required slopes.
Now, finding the coordinates of the points from the graph :
Coordinates of A = (-7,4)
Coordinates of C = (-4,10)
Coordinates of D = (-10,8)
Coordinates of G = (-1,-4)
Now, slope (m) between two points is given by :


Hence, Option D is correct.
