Question

What is the rate of change of the linear function below?
9x – 2y = -10

Answer 1

The rate of change for the linear equation is

y= 9/2x + 5

The rate of change is 9/2x

Explanation:

Slope intercept form is y= mx + b

Step 1: 9x - 2y=-10

Step 2: 9x - 2y - 9x= -10 - 9x

Step 3: -2y =-10 - 9x

Step 4: -2y/-2=-10/-2 - 9x/-2

Final Step: y=9/2x + 5
