Question

I need to know which ones are parallel and which ones are perpendicular and the steps thank youu

Answer 1

Answer:

If both equations have the same slope, they are said to be parallel.

If an equation is the reciprocal of another equation (meaning flipped denominator and numerator as well as flipped +/- sign) they are said to be Perpendicular.

Hope it helps!

Answer 2

Parallel lines will have the same slope! Perpendicular lines have opposite reciprocal slopes (opposite signs and reciprocal)

y = mx + b where m is the slope

The first and last equations have 2 as their m value and therefore are PARALLEL

Since the second equation has -1/2 which is the opposite reciprocal of 2, it’s PERPENDICULAR to the other two lines :)
