A rectangular pool surrounded by a walkway is enclosed in a backyard. The enclosed section covers an area of 300 square feet, and the width is 5 feet shorter than the length. The walkway has width x feet. Given the formula A=(20−2x)(15−2x), what does (15−2x) represent in this context?

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
