Question

What is the rate of change in Y=4x-7

Answer 1

4

Explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 4x - 7 ← is in slope- intercept form

with slope m = 4

For a linear function the slope is the measure of it's rate of change.

Thus rate of change is 4
