A cell phone provider will allow you to buy a phone over time. They require a $50 initial payment and then charge $25 per month. If this situation were represented by a function, what would be the slope?

25

Step-by-step explanation:

Given that:

Initial payment done for buying the phone = $50

Charges per month for the phone = $25 per month

To find:

The equation to represent the situation and its slope.

Solution:

First of all, let us assume that represents the number of months for which monthly is to be made.

Charges paid for one month = $25

Charges paid for months =  $25

Total cost of the phone = Initial payment + Charges paid for months

It is a linear equation between two variables and .

This equation can be compared with slope intercept form of a line.

Slope intercept form of a line is represented by:

is the slope.

On Comparing, we get:

Therefore, the slope is 25.
