Pls help you dont have to explain just answer

Problem 1:  g(x) = (x - 3)(x + 18)

Problem 2:  Option A, y = 1.2x - 6

Problem 3:  Option D

Step-by-step explanation:

Problem 1:

g(x) = x^2 + 15x - 54

g(x) = (x - 3)(x + 18)

 Option B, g(x) = (x - 3)(x + 18)

Problem 2:

Slope = 1.2

(y - y1) = m (x - x1)

(y - 0) = 1.2(x - 5)

y = 1.2x - 6

 Option A, y = 1.2x - 6

Problem 3:

 Option D

Look at attached graph:  

answer:   y=2x-3

step-by-step explanation:

one set of data has more variation than the other. hope this !
