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.

Answer:
Step-by-step explanation:
7 with exp 3 times 9 with exp 4 minus 2=
343 times 6561 minus 2=
2250421
Finding gradient:
m = y2 - y1
x2 - x1
= -1 - 6
1 - 3
= -7 / (-2)
= 7/2
y = m(x - x1) + y1
y = 7(x - 3) + 6
2
2y = 7x - 21 + 12
2y = 7x - 9

It took 8 weeks because follow 15 to the dot then go down and you see the answer
You would do 20 • 3=60 and the you would add 20 • 1/5=4 so, your total is 64in.
