Question

Felicia paid $125 to join a tennis club. She pays an additional $5 every time she uses on of the tennis club occurs.

State what x and y represent in context

What is the y-intercept for the question and explain what it represents in context​

Answer 1

You can model the situation you described as

$y=125+5x$

Where $y$ represents the money spent, and $x$ the number of uses.

The $y$ intercept is 125, which represents the money spent without using the club even once. In fact, to find it you set $x=0$, i.e. zero usage.
