The answer to the question is d
Answer:
The inverse function is y=x−24 .
Step-by-step explanation:
For this case we have that the equation of a line of the slope-intersection form is given by:

Where:
m: It's the slope
b: It is the cut-off point with the y axis
In this case we have the following data:

Then, the equation is of the form:

We find "b" replacing the point:

Thus, the equation is:
