Question

Please Help Me =(

Answer 1

Answer:

-21 = slope

-69 = intercept

Step-by-step explanation:

Given the function :

f(x) = - 7x +. 9

Suppose you add 2 to the input of f to create a new function g,

Add 2 to the input of f to create g

g(x) = f(x + 2) = 7(x +2) + 9

g(x) = 7x + 14 + 9

g(x) = 7x + 23

then multiply the output of function g by –3 to create function h.

h(x) = - 3(g(x)) = - 3(7x + 23)

h(x) = - 21x - 69

What are the slope and y-intercept of the graph of function h?

The slope and y intercept are :

From y = mx + c ; comparing the relation ;

Where m = slope ; c = intercept

m = - 21 = slope

c = -69 = intercept
