Question

Look at the graph of the linear function. On a coordinate plane, a line goes through 4 points. Point A is (negative 2, negative 4), point B is (negative 1, negative 2), point C is (1, 2), and point D is (2, 4). The rate of change between point A and point B is 2. What is the rate of change between point C and point D?

Answer 1

D

Explanation:

Answer 2

2

Explanation:

For a linear function, the rate of change is the same everywhere. It is the same between points C and D as it is between points A and B: 2.

The rate of change between points C and D is 2.
