Question

Please Dont Skip Over My Question, Please Help Me. ;(

Let f(x) = –7x + 9. Suppose you add 2 to the input of f to create a new function g, then multiply the output of function g by –3 to create function h. What are the slope and y-intercept of the graph of function h?


slope =
y-intercept =

Answer 1

Answer: slope = 21, y-int = 15

Explanation:

f(x) = -7x + 9

g(x) = -7(x + 2) + 9 = -7x - 5

h(x) = -3(-7x - 5) = 21x + 15

slope = 21

y-intercept = 15

hope this helps (not sure if my answer is correct)
