4) Elyse has $18 on a gift card that she can use to rent movies online. The graph at the right shows the amount of money remaining on her gift card based on the number of movies she rents. Find the unit rate of the graph, and describe what it means in the context of the situation.

• m=3; Each movie costs $3 so her gift card will decrease $3 each time.

• m=-3; Each movie costs $3 so her gift card will decrease $3 each time.

• m=3; Each movie costs $3 so her gift card will increase $3 each time.

• m=-3; Each movie costs $3 so her gift card will increase $3 each time.

Answer explanation

The line is decreasing from left to right so the slope is negative, which means her card will decrease $3 with each use.

5) What is the relationship of the triangles on this line?

• They are similar

• They are congruent

• The slope of the large triangle is greater than the slope of the small triangle

• They are cousins

6) Explain whether or not these two triangles could lie on the same line.

• Yes: because the 18/10 = 2/3

• No: because the 18/10 ≠ 2/3

• Yes: because the 10/18 = 2/3

• No: because 10/18 ≠ 2/3

7) Could these two triangles both lie on a line that has a slope of 6?

• No; because 7/42 and 5/30 both = 1/6

• Yes; because 7/42 and 5/30 both = 1/6

• No; because neither 42/7 or 30/5 = 6

• Yes; because both 42/7 or 30/5 = 6
