Part D Does the graph match your prediction? How so? If your graph doesn’t match your prediction, explain why. Use a straight edge to determine where your graph crosses the x- and y-axes. Part E
This table shows the prices of the three TVs in addition to their length and width. Is the price of a TV proportional to the length of its screen? How do you know?

Length (inches) Width (inches) Price
16
9
$160
20
11.25
$180
24
13.50
$200

Part F
Think about graphing the relationship between the length of the TV screen and the price. What do you predict the graph would look like?
Part G
Go to your Math Tools and open the Graph. Graph the relationship between the screen length. Before you begin, clear any previous data entries and graphs. Be sure to set the origin for your graph by entering 0 for price and 0 for length for one of the points.

When you’re satisfied with your graph of price versus length, take a screen capture of it and paste it in the answer field.

Part H
Does the graph match your prediction? Why or why not? Use a straight edge to determine where your graph crosses the x- and y-axes.
