Use the data in the table to model and complete the graph. y Number of weeks, x 60 50 40 30 20 10 Weight of pig in kg, y 0 32 Weight in kilograms 1 38 2 44 50 3 x 4 56 0 1 2 3 4 5 Weeks

  30. Section 1.9 Checkpoint 15Using a Graph to Make a Prediction Use the graph to answer the questions below. Write the ordered pair (x, y) that represents the ticket cost for 5 people to attend the game. How much will 5 tickets cost? The graph shows the ticket cost for people attending a football game. y 30 25 20 15 10 5 $20 Draw a line through the points and use it to predict the ticket cost for 8 people. Ticket Cost ($) About $32 x 1 2 3 4 5 6 7 8 People
