Question

Find the shape, or rate of change, from the following table?

Answer 1

ANSWER

C. -6

EXPLANATION

The rate of change is the change in the dependent variable when the independent variable changes 1 unit. In this case, all columns in the table have a change in the x variable of 1, so the difference between each column in the y-row is the rate of change,

$m=-9-(-3)=-15-(-9)=-21-(-15)=-6$

Hence, the rate of change is -6.
