Answer 1

Answer is A on edg

Explanation:

The slope of the graph is 2.50, and it represents the cost of each movie.

Answer 2

x y
# of movies Total Cost
9 27.50
12 35.00
15 42.50
22 60.00

Run or change in x: 9 - 22 = -13
Rise or change in y: 27.50 - 60 = -32.50

Slope = Rise / Run
Slope = -32.50 / -13
Slope = 2.50

The slope is 2.50, and it represents the cost of each movie.
