6=−s+776, equals, minus, s, plus, 77 given the above equation, what is the value of 1+5(77-s)1+5(77−s)1, plus, 5, left parenthesis, 77, minus, s, right parenthesis?

1 is c

2 is a

3 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)
