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)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/e9lgdayfzr27dyurvzbw9lffpiv7535tiv.png)
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)](https://img.qammunity.org/2021/formulas/mathematics/high-school/4ns42ccc5k4ofzmwh2jfwed2h3y8dhujow.png)
Simplifying the terms, we have,
![m=(150)/(2)](https://img.qammunity.org/2021/formulas/mathematics/high-school/fxpkj5gi86h4th1lgyoba0v2wqyaxc7x35.png)
Dividing the terms, we get,
![m=75](https://img.qammunity.org/2021/formulas/mathematics/high-school/3n6b3or8k1grshpxfue2vybo75t8ykg6nk.png)
Thus, the slope of the table is
![m=75](https://img.qammunity.org/2021/formulas/mathematics/high-school/3n6b3or8k1grshpxfue2vybo75t8ykg6nk.png)
The slope represents the rate of change of charges for repairing the car per hour.
