On a graph, parallel equations will run forever and never touch, whereas, perpendicular equations will make a right angle with each other.
In an equation, parallel lines will have the same slope (the mx part of the equation).
Ex:
y = (1/3)x + 2
y = (1/3)x + 4
Perpendicular equations have negative reciprocal slopes of each other.
Ex:
y = (3/5)x + 6
y = -(5/3)x + 4

perpendicular cross parallel do not
Parallel lines never intersect and remain equal distance from each other but perpendicular lines intersect at right angles
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 (=)
There is no relationship between the slopes of parallel or perpendicular lines and their y-intercepts.
No but parallel lines have a constant distance between them
