Question

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

Answer 1

if you look closely at the line, the equation itself is y=-2x-4. Now you have to find the system that corresponds with that. What do you think it is @shannon342 ?

Answer 2

I think it is A

Answer 3

actually. 2x+y=-2 does not equal y=-2x-4

Answer 4

however, in answer B., both of the equations indeed work for y=-2x-4

Answer 5

-8x-4y=16
+8x +8x
----------
-4y=8x+16
/-4 /-4 /-4
---------
y=-2x-4

Answer 6

and for the other equation...

-4x-2y=8
+4x +4x
----------
-2y=4x+8
/-2 /-2 /-2
--------
y=-2x=4

Answer 7

therefore, B. is the correct answer. Does that make sense @shannon342 ?

Answer 8

Yes Thank you

Answer 9

anytime ^.^
