500 feet of fencing material is available to enclose a rectangular field. One side of the field is bordered by a river and does not need to be fenced. Find the dimensions of the field that will enclose the largest area. Note that in addition to finding the dimensions, you must also show your justification for WHY these values provide the maximum according to the First Derivative Test for Absolute Extrema.

the answer is a

step-by-step explanation:

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
