Question

Help with the perpendicular lines please

Answer 1

Answer:

Red and Green are parallel

Black and Blue are perpendicular

Step-by-step explanation:

Parallel lines need to have the same slope. Lines red and green both have a slope of 1/2.

The slopes of two lines that are perpendicular have to be opposite reciprocals, and must be multiplied together to get -1. Line black has a slope of -4, and line blue has a slope of 1/4. Both of them multiplied together equals -1.
