Question

A.Because the rate of change is constant, the function is linear

B.Because the rate of change is constant, the function is nonlinear
C.Because the rate of change is not constant, the function is linear
D.Because the rate of change is not constant the function is nonlinear

Answer 1

A is true.

Explanation:

Rate of change = difference in y / difference in x

= (7-8)/ 10/8) = 1/2

also 11-8/16-10 = 1/2

and 14-11/22-16 = 1/2.

The rate of change is constant.

Answer 2

A, the function is linear, and the ROC is constant.
