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
