The answer will be A
Step by Step Calculation
Length = √((x2 - x1)2 + (y2 - y1)2)
= √((-8-(4))2 + (7-(2))2)
= √(144+25)
= √(169)
= 13
The correct answer is: <span>D. The regression line is not a good model because the points in the residual plot form a curve. (i know this because i just passed the test ;) )</span>
X has infinity solutions.
Angle Y would be 40 degrees
