The county fair charges $1.25 per ticket for the rides. star bought 25 tickets for the rides and spent a total of $43.75 at the fair. star spent her money only on ride tickets and fair admission. the price of the fair admission is the same for everyone. write an equation in slope-intercept form to represent the cost for anyone who only pays for ride tickets and fair admission. use y to represent the total cost and x to represent the number of ride tickets.

First you will have to calculate how much the fair admission costs were.
Star spent $43.75 on rides and the admission together.
One ride ticket costs $1.25, so 25 ride tickets cost:
1.25 x 25 = $31,25
The admission costs will then be:
43.75 - 31.25 = $12.50
A normal linear equation goes like this:
y = c · x
x is supposed to be the number of ride tickets. you add the costs of those tickets in front to show how much money it will be.
y = c · 1.25x
Your constant in this case is the admission, it is the same for everyone, $12.50, so your equation will be:
y = 12.5 · 1.25x

It means if x is -1 what is y then . check -1 on x axis and then check the value of y when x is -1
