To find the monthly cost (slope), we need to calculate the change in cost divided by the change in number of months.

The change in cost is $149 - $74 = $75.
The change in number of months is 4 - 1 = 3.

Slope = Change in cost / Change in number of months
Slope = $75 / 3
Slope = $25

Therefore, the slope or monthly cost is $25.
