Based on the least-squares regression and residual plot, is a linear model suitable for this data set?
O Alinear model is suitable because the value of r is
close to 1.
A linear model is suitable because the residual plot
shows a curved pattern.
A linear model is not suitable because the residual
plot shows a clear pattern.
O A linear model is not suitable because there are more
positive residuals than negative residuals.

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|

the answer will be b x² +x-1
