Mathematics
1 answer:
LekaFEV [45]3 years ago
6 0

Answer:

Part A: y=5x

Part B: B and D

Step-by-step explanation:

The ratio of the number of cases to the total cost is 1:5. So, an equation that can be modeled by this situation in slope-intercept form is y=5x.

The unit rate actually does equal the constant of proportionality, so this is not true.

The unit rate of the number of cases per dollar is 1/5, so this is true.

No, the graph starts on the origin, so this isn’t true.

Points (0,0) and (1,5) are on the graph, so this is true.

25 cases will not cost $120, they will cost $125.
