Answer:

Step-by-step explanation:

f(x)=40
x=8
so if x=2 it would be 40/8 which is 5
The answer is (6,-4). By the way, this was very hard to read.
Find the difference in the y-coordinates: -3 - 1 = -4
Find the difference in the x-coordinates in the same order: 2 - 5 = -3
Divide the difference in y by the difference in x: slope = (-4)/(-3)
Reduce the fraction: slope = 4/3
