Answer 1

To find the slope (or the monthly cost) from the table, we can determine the change in cost per month.

From the table:

• The cost increases from $74 (1 month) to $99 (2 months).

• The increase in cost from month 1 to month 2 is: \[ 99 - 74 = 25 \]

• The cost increases from $99 (2 months) to $124 (3 months).

• The increase in cost from month 2 to month 3 is: \[ 124 - 99 = 25 \]

• The cost increases from $124 (3 months) to $149 (4 months).

• The increase in cost from month 3 to month 4 is: \[ 149 - 124 = 25 \]

The monthly increase in cost is consistently $25.

Therefore, the slope, or monthly cost, is $25.
