Question

This graph represents a proportional relationship between the number of months, x, data is used on a cell phone and the total cost of data usage, y.
The equation that represents the graph above is y =
x.

The cell phone company decides to raise the data prices to charge $90 every 2 months. The new equation that would represent this relationship is y =
x.

Answer 1

Answer:

The equation that represents the graph is y = 40x

The new equation would be y = 45x

Step-by-step explanation:

As y increases by 40, x increases by 1, so 40/1, or 40

New equation: $90 per 2 months, y = 90, x = 2, 90/2 = 45
