Answer:

b. 65

a. The notation f(-2) means that we want to evaluate the value of the equation when x = -2

Step-by-step explanation:

A. The notation f(-2) means that we want to evaluate the value of the equation when x = -2

B. We will simply substitute the value of 2 for x

f(x) = 6(8-x) + 5

f(-2) = 6(8 - (-2)) + 5

f(-2) = 6(8 + 2) + 5

f(-2) = 6(10) + 5 = 60 + 5 = 65

erastova [34]
Slope = y2 - y1/x2 - x1
          = -3 - (-1)/8 - (-2)
          = -3 + 1/ 8 + 2
          = -2/ 6
          = - 1/3

hope this helps :)
