Question

Function 1: y = 4x + 5

Function 2: The line passing through the points (1, 6) and (3, 10).

Which of these functions has the greater rate of change?

Answer 1

B

Hope this helps!

Answer 2

B

Explanation:

The rate of change is the slope. Function 1 has a slope of 4. Function 2 has a slope of:

m = Δy / Δx

m = (10 - 6) / (3 - 1)

m = 4 / 2

m = 2

So function 1 has the greater rate of change. Answer B.
