Question

Determine if the lines that pass through the given points are parallel, perpendicular or neither. Line A: (-3, 5) and (0, 7) Line B: (6, 2) and (9, 4).

Answer 1

find slope of both of the lines, if they are equal, then lines are parallel.
if product of slopes = -1 then lines are perpendicular
else neither

so first find slope of both lines!
