If h(r)=2/3r-6, what is the value of h(-9)

 The required value of h(-9) is -12.

Step-by-step explanation:  We are given the following function :

We are to find the value of h(-9).

To find the value of h(-9), we need to substitute r = -9 in equation (i).

From equation (i), we get

Thus, the required value of h(-9) is -12.
