I REALLY NEED THIS RIGHT NOW PLEASE HELP Are the given lines parallel? How do you know? y=2 and y = -4

Novay_Z [31]

Answer:

Yes, they have the same slope

Step-by-step explanation:

Both y=2 and y=-4 have the same slope, a slope of zero, because when they are graphed, both of them form a straight horizontal line. And since they both form a straight horizontal line, they are parallel because they have the same slope.

Hope this helped! :)
