The slope, or monthly cost, can be found by taking the change in cost divided by the change in number of months.
Change in cost: $149 - $74 = $75
Change in number of months: 4 - 1 = 3
Slope = Change in cost / Change in number of months
Slope = $75 / 3
Slope = $25
Therefore, the monthly cost is $25.
