Question

Determine which of the following function have a positive rate of change. Explain your answer.

y=2x-11

Answer 1

y = 2x - 11

Explanation:

The "rate of change" is the coefficient of x when the function is written in this form:

y = mx + b

That coefficient will be positive when the function has a positive rate of change.

y = 2x - 11 . . . has a positive rate of change
