Answer:

I believe the answer is D, Because the lines are intercecting.

Step-by-step explanation:

Answer:

C) perpendicular lines

Step-by-step explanation:

-2x+2y=5  .....(1)

2y = 2x + 5

y = x + 5/2

Y = mx + b   where mis the slope m₁ = 1

-10x-10y=5 .....(2)

10y = -10x -5

y = - 1 - 1/2          m₂ = -1

m₂ = - 1/ m₁

those 2 line should be perpendicular
