Question

Determine if the lines that pass through the given points are parallel, perpendicular or neither.
Line A: (-8, 8) and (-5, 10) Line B: (-7, 12) and (-5. 15)


Paralle

Perpendicular

Neither

Cannot be determined

Answer 1

Find the slopes of the lines.
The lines are parallel if the slopes are equal.
Perpendicular if their product is -1.

Answer 2

is it parallel?

Answer 3

i think..if my math is right

Answer 4

because the slopes are 2/3 and 3/2

Answer 5

Let's see.
\[m_A={10-8\over-5-(-8)}={2\over3}\].
\[m_B={15-12\over-5-(-7)}={3\over2}\].
Since \[m_A \neq m_B\] and \[m_A m_B \neq -1 \] then they are neither parralel nor perpendicular.

Answer 6

oh i thought they would be parallel because there the same numbers

Answer 7

Not really. The numbers must also be in the same positions. :D

Answer 8

oh okay ! thank you could you help me on two others?
