Question

Determine if lines that pass through the given points are parallel, perpendicular or neither.

Line A: (5, 4) and (7, 5) Line B: (4, -5) and (8, -3)

a) Parallel

b) Perpendicular

c) Neither

d) Cannot be determined

Answer 1

Find the slope of each line

Line a:


`(5-4)/(7-5)`

`(1)/(2)`

Line b:


`(-3-(-5))/(8-4)`

`(2)/(4)`

`(1)/(2)`

So the lines given are parallel since both of their slopes are the same.

Hope this helps :)
