Answer:
1. what is a residual?
A. A residual is a value of y -y, which is the difference between an observed value of y and a predicted value of y.
2. The regression line has the property that the_sum of squares_of the residuals is the minimum possible sum.

2. In what sense is the regression line the straight line that "best" fits the points in a scatterplot?
The regression line has the property that the_sum of squares_of the residuals is the minimum possible sum.

The formulat for finding the slop is
m = (y2 - y1)/(x2 -x1)
so if we put the values of our two given points
m = (-13 -12) / (5 - 5) = -25/0 = undefined
so our slop is undefined which means it is a vertical line
Answer:
yes
Step-by-step explanation:
same slope
