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

4

Step-by-step 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
