Part A Write an equation representing the area Bruce covered, y, in terms of the number of tiles he used, x.

Part B
Write an equation representing the area Felicia covered, y, in terms of the number of tiles she used, x.

Part C
The person whose equation has the greater unit rate is the person whose tiles cover the most area per tile. Whose equation has the greater unit rate?

Part D
Using the slope-intercept program, enter the slope and the y-intercept for Bruce’s equation. Click Save Line, and then enter the slope and y-intercept for Felicia’s equation. Paste a screen shot of the image here.

Part E
Which line is steeper, Bruce’s or Felicia’s? Whose slope is greater? Does this match the comparison from Part C?

Part F
What does the greater unit rate, or slope, mean in terms of the situation? What can you conclude from this?
