Which shows the best use of the associative and commutative properties to make simplifying - 5+9 - $ + 2 easier?
A. [2+ i +(-5)] + [(-4) + 9]
O B. (1+9+(-5)] + [2+(-3)
OC. (8 +(-
5)] + [9+(-4) + 2]
OD. [å +(-X)] + [9+2+(-5)]

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)

faster, im not sure why but i know it is faster
