The residual plot for a data set is shown. Based on the residual plot, which statement best explains whether the regression line
is a good model for the data set and why?
A.)The regression line is not a good model because there is no pattern in the residuals.
B.)The regression line is not a good model because only one point in the residual plot is on the x-axis.
C.)The regression line is a good model because the points in the residual plot are close to the x-axis and randomly spread around the x-axis.
D.)The regression line is a good model because the residuals approach 0 as x increases.

Given:
A(16, 4)
B(34, 40)
Line segment AB partition in the ratio 1 : 5.
To find:
The coordinate of a point that partitions AB.
Solution:
Section formula:
Here and m = 1, n = 5
The coordinate of point that partitions the segment AB is (19, 10).
Answer:
The answer is
Step-by-step explanation:
The slope of a line given two points can be found by using the formula
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(-4,7) and (-1,3)
We have
We have the final answer as
