Question 101 points)which equation in slope-intercept form represents the line that passes through (5, 1) and(-4,7)

On a piece of paper graph f(x)=5•(0.4)^x

The length of a rectangle is x times the square root of 100. the width is one-half y more than three-halves x. given that the area of the rectangle is 125 cm2, which equation could represent the rectangle in terms of x and y? a) 5xy − 15x = 125 b) 5xy + 15x = 125 c) 15x2 − 5xy = 125 d) 15x2 + 5xy = 125
