Caroline is going to the state fair with a group of friends. It costs her $12 for admission, and once she is inside the fair she can buy tickets for $0.75 each in order to play games, purchase food, or go on rides. a. Write an equation to represent the relationship between the total cost, y, and the amount of tickets, x, she buys. b. What is the slope, or rate of change? c. What is the y-intercept? d. Describe what a graph of this relationship would look like.

a) y=0.75x+12    (y=ax+b)

b)a=0.75

c)b=12 (b=y-intercept, the place where the graph hits the Y axis). It's the starting cost, the cost that will be paid only one time

d) starts at (0,12) and goes up +0.75 each time

your answer is...

Step-by-step explanation:

a) y=0.75x+12

b)a=0.75

c)b=12 (b=y-intercept, the place where the graph hits the Y axis). It's the starting cost, the cost that will be paid only one time

d) starts at (0,12) and goes up +0.75 each time
