A perpendicular line is a line that creates two 90 degree angles at the line, segment, etc. that it intersects. Parallel lines are two lines that never intersect.
Perpendicular lines cross at right angles (+)
Parallel lines will never meet, no matter how far they are extended (=)

Is 2x equals y plus 8 a parallel line or a perpendicular line?
One single line is never parallel or perpendicular. Those words tell you somethingabout the relationship between two lines.
Is -x plus 2y equals 6 a parallel line or a perpendicular line?
One single line is never parallel or perpendicular. Those words tell you somethingabout the relationship between two lines.
What is the relation between two lines perpendicular to the same line?
They're parallel.
How do you construct a parallel line using a perpendicular line?
Start with a line, L1. Draw a line perpendicular to it, L2. Next draw a line perpendicular to L2, but not the same as L1. This last line will be parallel to L1.
Is a line which intersects two parallel lines?
No they are perpendicular if the intersect at a right angle. + is perpendicular, = is parallel
