rate of change between A and C :
slope = (y2 - y1) / (x2 - x1)
A = (1,-3)....x1 = 1 and y1 = -3
C = (3,5)...x2 = 3 and y2 = 5
now sub
slope = (5 - (-3) / (3 - 1)
slope = (5 + 3) / 2
slope = 8/2
slope = 4

rate of change between A and B
slope = (y2 - y1) / (x2 - x1)
A = (1,-3)...x1 = 1 and y1 = -3
B = (2,0)...x2 = 2 and y2 = 0
now sub
slope = (0 -(-3) / (2 - 1)
slope = (0 + 3) / 1
slope = 3

rate of change (slope) of A and C is 4
rate of change (slope) of A and B is 3

so A and C is greater then A and B
