Question

What do the following two equations represent? -2x+2y=5 and -10x-10y=5

Choose 1 answer:
A) equal lines
B) parallel lines
C) perpendicular lines
D) none of the above

*40 points*

Answer 1

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

Explanation:

Answer 2

C) perpendicular lines

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
