Determine from the given points of two lines if the lines are parallel, perpendicular, or neither. Enter your answers below. Use a
forward slash (i. e. "l) for all fractions (e. g. 1/2 for 3).
o Line a: (-3,1) and (-7, -2)
o Line 6: (2,-1) and (8,4)
Solution
Find the slope of each line. Use a forward slash (i. e. /) to make a
fraction (e. g. -1/2 is the same as -B).
o The slope of Line a is
-3/6
o The slope of Line bis
