The slope of the table is $75 and the slope represents the rate of change of charges for repairing the car per hour.
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,
From the table, we shall consider the coordinates (0,15) and (2,165)
Let us substitute these two points in the formula, we get,
Simplifying the terms, we have,
Dividing the terms, we get,
Thus, the slope of the table is
The slope represents the rate of change of charges for repairing the car per hour.
