You want to join your local gym, because they offer classes on yoga, kick boxing, andcycling. When you stop by to find out how much it will cost, they tell you that to join the gym,there is a monthly fee of $25 plus $5 per class you attend. What is the rate of change/(slope) ofthis problem?

Respuesta :

we know that

The equation of the line in slope intercept form is equal to

y=mx+b

where

m is the slope or unit rate

b is the y-intercept or initial value

In this problem we have

m=$5 per class

b=$25

so

y=5x+25

where

x is the number of class

y is the total charge

therefore

the answer is

the rate of change is $5 per class
