Question

A plumber charges $45 per hour, plus a one-time fee for making a house call. The total fee for 3 hours of service is $285. Write the point-slope form of an equation to find the total fee y for any mumber if hours

Answer 1

y - 285 = 45(x - 3)

Explanation:

Answer 2

y - 285 = 45(x - 3)

Explanation:

The given point is (hours, fee) = (3, 285), and the slope is given as 45 per hour.

The point-slope form of the equation for a line is ...

y - k = m(x - h) . . . . . . . for a slope m and a point (h, k)

Using the given values, and letting x stand for the number of hours, the equation is ...

y - 285 = 45(x - 3)
