The cost of a gym membership can be represented by 25 + 5x, where x is the number of visits to the gym.

Question

options:

The y-intercept is ___________. This means that

The slope is ___________. This means that ________

Answer 1

In the equation for the cost of a gym membership, $C=25+5x$:

1. The y-intercept is 25. This means that if a person does not visit the gym at all ($x=0$), they still have to pay a base fee of $25 for the membership.

2. The slope is 5. This means that for each additional visit to the gym ($x$ increases by 1), the cost increases by $5. In other words, every time the individual goes to the gym, they incur an additional cost of $5.
