Question

The graph of a function is a line that passes through the coordinates

Answer 1

Answer:

The rate of change of the function is 9

Step-by-step explanation:

Mathematically, the rate of change of the function refers to the slope of the line that passes through the given points

Thus, we use the slope equation as follows;

m = (y2-y1)/(x2-x1)

(x1,y1) = (6,6)

(x2,y2) = (7,15)

Substituting these values, we have

m = (15-6)/(7-6) = 9/1 = 9
