Answer:

Step-by-step explanation:

The inverse is found by interchanging the x and y of the original and then solving for y.

y = 2x + 4               Interchange x and y

x = 2y + 4               Subtract 4 from both sides

x - 4 = 2y                Divide the entire equation by 2

x/2 - 4/2 = 2y/2

x/2 - 2 = y or

y = x/2  - 2
