Asystem of equations has 1 solution. if 4x – y = 5 is one of the equations, which could be the other equation? y = –4x + 5 y = 4x – 5 2y = 8x – 10 –2y = –8x – 10

y = –4x + 5 (A) is the answer

answer: i cant see the picture

step-by-step explanation:

can u take a better picture

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)
