Answer:
Explanation:
The cost of belonging to the gym can be modeled by C(m) = 50m + 79.50, where C(m) is the total cost for m months of membership. This is a linear function. Recall, the standard form of linear equation is expressed as
y = mx + c
where
m is the slope or rate of change
c is the y intercept. It is the value of y when x is 0
By comparing both equations,
slope = 50
y intercept = 79.5
The slope means that the amount charged per month by the gym is 50
When number of months, m = 0, total cost = 79.5. Thus,
The y intercept, 79.5 is a base fee charged by the gym
