Question

A relation is plotted as a linear function on the coordinate plane starting at point A (0, 3)and ending at point B (2, 7) .

What is the rate of change for the linear function and what is its initial value?

Select from the drop-down menus to correctly complete the statements.
The rate of change is____ and the initial value is___ .

Answer 1

The rate of change is 2 and the initial value is 3.

Explanation:

took the unit test

Answer 2

To calculate the rate of change, we simply use the formula to get the slope of the line, so:
rate of change = (7 - 3) / (2 - 0)
rate of change = 2

The initial is just the value of x at the first coordinate. So, the initial value is 3.
