Select the system of equations that corresponds to the given graph. A. -2x - y = 4 2x + y = -2 B. -8x + 4y = -16 -4x + 2y = -8 C. x - 2y = 6 -2x + y = 4 D. 2x + 3y = 6 3x + 2y = 4

i see parallel lines so they must have the equations have to have the same coefficients for x and y

OpenStudy (lgbasallote):

that means it's not C or D

OpenStudy (anonymous):

parallel lines have the same slope

OpenStudy (lgbasallote):

it's not A either because the coefficient of x is -2 and 2 <--not the same

OpenStudy (lgbasallote):

so what remains?

OpenStudy (anonymous):

B!!!!!

OpenStudy (lgbasallote):
