Wis between x and y on xy. wx = x + 10, wy = x - 6, and xy = 10. which of the following equations could be used to find the value x?

1. x + 10 = 10

2. x - 6 = 10

3. (x + 10) + (x - 6) = 10

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

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)
