Question

Which of the following equations form a dependent system with line A which has the equation y = (-1/2) x + 4.

A. 2x + 4y = 16
B. x - 4y = 8
C. 2x - 4y = -16
D. x + 4y = -8

Answer 1

if you multiply that equation all the way across by 2 you get
\[2y=-x+8\] see if you can turn that in to one of the choices below

Answer 2

ok i see now all your choices have \(4y\) so instead of multiplying the first equation by 2, multiply it by 4 and get
\[4y=-2x+16\] then try to match that one up

Answer 3

hint, don't look beyond the first choice

Answer 4

So A lol @satellite73
