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

Respuesta :

Find the slope of each line

Line a:

[tex] \frac{5-4}{7-5} [/tex]
[tex] \frac{1}{2} [/tex]

Line b:

[tex] \frac{-3-(-5)}{8-4} [/tex]
[tex] \frac{2}{4} [/tex]
[tex] \frac{1}{2} [/tex]

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

Hope this helps :)
