We can see that

both lines intersects at origin

so, the solution is x=0 and y=0

now, we will check each options

option-A:

[tex] y=2x [/tex]

[tex] y=-4x [/tex]

now, we can set them equal

and then we can solve for x

[tex] -4x=2x [/tex]

[tex] 6x=0 [/tex]

[tex] x=0 [/tex]

now, we can find y

[tex] y=2*0 [/tex]

[tex] y=0 [/tex]

so, solution is x=0 and y=0

so, this correct...........Answer
