help pls with 2 problems!!
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
@wolfe8
is it C?? thats what i got
I would put in x=0 to all eqations and see which pair gives y=2
Awnser is D i did my work and the first one y equals 4 and the second one y equals -4 so its D @wolfe8
What?? But you want y=2 when x=0! See in the graph? The lines intercept at y=2 when x=0
i dont know im confused i thought it would be D
Let me eat first
ok
Ok I finished eating. So, take a look at the graph. Notice an important part of it - where both lines intersect each other at (0,2). So, since you are given choices, you can substitute x=0 into your options and see which pair both gives y=2.
so its y = 2
its C
Both of the equations have to give the same result. In C one of them gives y=-3
oh so it has to be a or b @wolfe8
Are you just guessing? Did you even try what I told you to?
yah plug in the numbers but now im guessing cause im getting confused my awnser was C but u said that wrongs
Replace x=0 into every single equation like this: -2(0)-y=4 2(0)+y=-2 And see what you get for y. The pair that gives you y=2 both is the answer.
