Question

What is the rate of change for this set of ordered pairs?

Answer 1

The rate of change for that set of ordered pairs would be 3 because the slope is 3. If this were a word problem, the answer would be 3 units per unit of time. ($3 per hour)

Answer 2

Option B.

Explanation:

If a line passes through two points, then the rate of change is

`m=(y_2-y_1)/(x_2-x_1)`

Consider any two ordered pairs from the given table.

Let line passes through (0,6) and (2,12).

`m=(12-6)/(2-0)`

`m=(6)/(2)`

`m=3`

The rate of change for this set of ordered pairs is 3.

Hence, he correct option is B.
