Given the linear regression equation y=−8.5x+99.2 when the length, y, of the rope after tying x knots.
Explain what the y-intercept means in the context of the problem. Explain what the slope means in the context of the problem.

Th perimeter of a rectangular garden is 150 feet. the length is 50 feet longer than the width, w. which equation could be used to calculate the width of the garden? a.) 2w+ 2(w-50) =150 b.) 2w+50 + 2w =150 c.) 2(w+50) + w =150 d.) 2w+ 2(w + 50) = 150 need asap. will give brainliest !
