If y = 4x – 1, which of the following sets represents possible inputs and outputs of the function, represented as ordered pairs? {(2, 5), (4, 12), (9, 25)} {(–3, –10), (0, –2), (6, –18)} {(7, 24), (–1, –9), (–8, 35)} {(1, 3), (–2, –9), (0, –1)}

c

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)
