Question

Can anyone help me with this please I really need help with this rq .

Answer 1

Explanation:

g(x) = ax - b

-76 = 27a - b

-79 = 28a - b Subtract

3 = -a Multiply both sides by -1

a = -3

g(x) = -3x - b

-85 = -3*30 - b

-85 = - 90 - b Add 90 to both sides

90-85 = - b Combine

5 = - b Multiply both sides by - 1

-5 = b

g(x) = -3x - b

g(x) = -3x - (-5)

g(x) = - 3x + 5
