What do the following two equations represent? -2x+2y=5 and -10x-10y=5
choose 1
a) equal lines
b) parallel lines
c) perpendicular lines
d) none of the above

*40 points*

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
