Answer:
y = 2x - 9
Step-by-step explanation:
y2 - y1 / x2 - x1
9 - (-1) / 9 - 4
10 / 5
= 2
y = 2x + b
-1 = 2(4) + b
-1 = 8 + b
-9 = b
Hi there! The answer is D.
Function
f(x) = 7x - 6.
To find the inverse we need to switch the places from x and y.
y = 7x - 6
x = 7y - 6
-7y = -x - 6
7y = x + 6
y = (x + 6) / 7
