Answer 1

To find the slope, we need to determine the rate of change in cost per month. We can do this by finding the difference in cost between two consecutive months and dividing it by the corresponding difference in the number of months.

Using the given table:

For the difference between the 1st and 2nd month:
Cost difference: $99 - $74 = $25
Number of months difference: 2 - 1 = 1

Slope: $25 / 1 = $25

Therefore, the slope or monthly cost is $25.
