Answer:

Let x represents the number of hours of labor and y represents the total charges.

Since, in the given situation,

The total charges = A fixed charge for house call + Extra charge per hours,

Fixed charge for house call = $ 45,

Extra charges for every hour = $ 25,

⇒ Extra charge for x hours = 25 x,

Thus, the total charges for x hours,

y = 45 + 25 x

Which is the required equation that will use to determine the amount to charge each customer.

By comparing this equation with y = mx + c,

m = 25

M=slope
In this case the slope would be $25
y=mx+b
y=25x+45

Answer: m=25
