Answer:
D. In a given year, the amount spent on repair decreases by 99 for each oil change the owner gets
Explanation:
From the equation given, the slope of the regression model is the Coefficient of x ; which is - $99 ; this means that we have a negative slope value and thus an increase in unit of x will lead to decrease of y, which is the amount spent. Hence, for every oil change athecar gets, the amount spent on repair that year decreases by $99
