What is the solution to this equation? 2x + x - 11 + 3 - 7x = 15
O -
A. x=-1
O B. - 13
O cx
O D. - 23
C. x=23

Step-by-step explanation:

2x + x - 11 + 3 - 7x = 15

-4x = 23

x = -23/4

add 5 subtract 1

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)
