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? –2 Negative one-half One-half 2

Answer 1

2

Explanation:

Answer 2

2

Explanation:

Point c is at (1, 2)

point d is at (2, 4)

rate of change formula

(f(d) - f(c))/2 - 1

f(2) = 4

f(1) = 2

4-2/1 = 2
