If you want to graph parallel lines, they need to have the same slope (Ex. 2x+2 and 2x+3)- parallel lines cannot have the same y-intercept because the two line would be the same.
Perpendicular lines slopes need have to be opposite reciprocals (Ex. -2x+4 and +1/2x+3)- perpendicular lines can have the same y-intercepts, it doesn't make a difference.

perpendicular.

PERPENDICULAR
How do you tell if lines on a graph are parallel?
two ways : 1. calculate the slope of the two lines, if it is same, they are parallel. 2. draw a perpendicular line ( 90 degrees) from on of the lines and if it intersects the other line at 90degrees then they are parallel -HD
Can perpendicular lines be parallel lines?
It is impossible for parallel lines to be perpendicular. Perpendicular lines are intersecting lines, meaning that they cross each other. Parallel lines, on the other hand, are lines that never meet, no matter how far they are extended in either direction. So intersecting lines (which includes perpendicular lines) and parallel lines are exact opposites. Parallel lines will never meet or cross; they cannot be perpendicular.
What is the opposite of perpendicular lines?
Parallel lines
