Answer 1

Answer:

B) The initial value is 22, and the rate of change is 15.

Step-by-step explanation:

The first point is located at (22, 54).  This means the initial value is 22.

The rate of change is found using the formula

$m=\frac{y_2-y_1}{x_2-x_1}$

Using the first two points, we have

$m=\frac{69-54}{37-22}\\\\=\frac{15}{15}=1$
