Answer:
The correct option is B.
Step-by-step explanation:
It is given that there is a strong, negative, linear relationship between x and y. where, x is the number of consecutive hours a worker has been assembling chainsaws and y is the number of chainsaws he can produce in an hour.
He finds that 70%of the variation in chainsaws produced per hour can be explained by the regression of y on x.


The slope is -0.7, therefore option B is correct.
Any point on the x-axis beyond the point (4, 0) is a possible cordinate of R.
X^3(1/y^2)-4 is (x^3y^-2)-4 simplified with only positive exponents
