Answer:
Step-by-step explanation:
If you're given a line, determine its slope.
Any parallel line you construct must have the same slope as does the given line.
Any perpendicular line you construct must have a slope which is the negative reciprocal of the slope of the given line.
Parallel lines have the same slope.
And perpendicular lines have negative reciprocal slopes. Ex. 2/3 x and -3/2x
