Answer:

Step-by-step explanation:
A linear function has the following format:

In which a is the slope(rate of change) and b is the y-intercept, that is, the value of y when x = 0.
Rate of change of 3
This means that 
So

A solution at (6, 12).
This means that when x = 6, y = 12. So



The linear function is:

Answer is 9
To get this answer, we replace h with 2, and replace r with 7. This is because h = 2 and r = 7 is given to us
So
h+r = 2+7 = 9
