Question

PLEASE.. 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)

Answer 1

do u know how to find the equation of a line when ur given 2 points?
also..do u know when 2 lilnes r called parallel?

Answer 2

Ah Trexy, use that same tool I gave you in the last question! :-D

Average slope:
\[m=\frac{\triangle y}{\triangle x}=\frac{y_2-y_1}{x_2-x_1}\]

Answer 3

Parallel means they'll have the same slope.

Perpendicular means they'll have inverse AND negative slopes (compared to one another)

Answer 4

Nevermind I got the answer already Thank You everyone

Answer 5

just find the slopes of the lines...

same slopes the lines are parallel

the the 2 slopes multiply to -1 then the slopes are perpendicular

or 1 slope is the negative reciprocal of the other

anything else then it would be neither

Answer 6

Example of inverse and negative:
\[-\frac{2}{3} \leftarrow \rightarrow +\frac{3}{2}\]

Answer 7
