interpret the slope y-intercept, if appropriate
An engineer wants to determine how the weight of a gas powered car, x, affects gas mileage, y. The accompanying days represent the weights of various domestic cars and their miles per gallon in the city for the most recent model year.
weight Miles per
(pounds), x Gallon, y
3797 16
3897 16
2704 24
3608 20
3360 22
3040 22
3787 17
2618 24
3509 18
3798 16
3399 17
interpret the slope y-intercept, if appropriate. Choose the correct answer below for y hat = -0.00661x + 41.80
a) A weightless car will get ____ miles per gallon, on average. It is not appropriate to interpret the slope.
b) for every pound added to the weight of the car, mileage in the city will decrease by _____ miles(s) per gallon, on average. It is not appropriate to interpret the y-intercept.
c) for every pound added to the weight of car, gas mileage in the city will decrease by _____ miles(s) per gallon, on average. A weightless car will get ____ miles per gallon, on average.
