greatest residual
I've got a math problem. It just shows me a picture of a scatter plot with plots and a line of regression with a negative correlation. It yaxia is the price of a used corolla and the xaxis is the age of the corolla.
I already figured out that the price goes down as the age of the car increases.
I also figured that the correlation coefficient and line of regression won't change if I change the xaxis to price and yaxis to age.
But I don't know how I can find the greatest residual of the xvalue that has an xscale of 1 and a range from 115 & to know if it will either be a positive or negative residual?
