Students at Mendel Middle School are planning a fair for their school’s fundraiser. Liam makes a poster for the fair. Maureen looks at the poster and says that the price per ticket decreases the more tickets a customer buys. Liam disagrees. Part A
The graph represents the relationship between the number of tickets bought and the price paid. Find the slope of the line using two different pairs of coordinate points. What does the slope mean about the price per ticket? Is Liam or Maureen correct?

Part B
What is the y-intercept of the graph? Explain what it means in the problem situation. Then write the equation for the line.
