The answer is... x = -7 or x = 1
Answer: a. −0.41
Step-by-step explanation:
The slope for the best-fitting linear equation is given by :-
where , =sum of squared deviations from the mean of X.
= correlation between y and x in terms of the corrected sum of products.
As per given , we have
Then, the value of the slope for the best-fitting linear equation will be
Hence, the value of the slope for the best-fitting linear equation= -0.41
So the correct answer is a. −0.41 .

2x + 5x + 5 = 180
7x + 5 = 180
7x = 175
x = 25
