Answer:
-4/3
Step-by-step explanation:
Before we can get the slope of AD, we need to get the coordinate of point D.
D(X, Y) = (5-3/2, 5-1/2)
D(X, Y) = (2/2, 4/2)
D(X, Y) = (1, 2)
Next is to get the slope of line AD
Slope = y2-y1/x2-x1
Slope= -2-2/4-1
Slope of AD = -4/3
Hence the slope of AD is -4/3
