How much does it cost if the plumber works for 6 hours?

Solution:

Let "y" be the total cost of the house call plus labor

Let "x" be the number of hours worked

A plumber charges a flat rate of $79 to make a house call and charges $78 for labor

The slope intercept form is given as:

y = mx + c

Therefore,

total cost of the house call plus labor = 79 + 78(number of hours worked)

y = 78x + 79

Thus the equation is found

How much does it cost if the plumber works for 6 hours?

Substitute x = 6 hours

y = 78(6) + 79

y = 468 + 79

y = 547

Thus it costs $ 547 if the plumber works for 6 hours
