Question

Patrick wanted to gather data about the cost of joining a community pool in his area. He plotted the data and determined that the average community pool membership cost consists of a one-time registration fee and a monthly fee modeled by the equation y = 15x + 40.
Identify and interpret the y-intercept in this model.

Answer 1

Answer:

40

Step-by-step explanation:

You can find y intercept by looking at the end of the equation, that’s what’s added. So +40 is the y intercept

The y intercept in this equation represents the one-time registration fee

Answer 2

The y intercept should be 40 as it’s the base you pay for the membership, and another $15 per month.
