The slope of the table is $75 and the slope represents the rate of change of charges for repairing the car per hour.

Step-by-step explanation:

Given that the car repair company charges a $15 fee for evaluation plus a rate for any services required.

We need to determine the slope.

The slope can be determined using the formula,


m=(y_2-y_1)/(x_2-x_1)

From the table, we shall consider the coordinates (0,15) and (2,165)

Let us substitute these two points in the formula, we get,


m=(165-15)/(2-0)

Simplifying the terms, we have,


m=(150)/(2)

Dividing the terms, we get,


m=75

Thus, the slope of the table is
m=75

The slope represents the rate of change of charges for repairing the car per hour.
