Question

5)A plumber charges $25 for a service call plus $50 per hour of service. Write an equation in slope-intercept form for the cost, C, after h hours of service.

Answer 1

Answer: your Answer is $75 dollars.

Explanation:

$25 + $50 = $75

Answer 2

`C = 50x + 25`

Explanation:

The $50 charge can be interpreted as the slope, as it varies based on the amount of time the service takes. The $25 can be interpreted as the y-intercept, as you'll get charged $25 no matter how long the service takes. Thus, we can plug these values into the slope-intercept form equation.

`y = mx + b\\C = 50x + 25`
