00:00

Thank you We sneak in and here's your smug too

00:05

Sure brought to you by parallel lines It was supposed

00:08

to be brought to you by perpendicular lines but they're

00:11

a little cross with each other right now are the

00:14

equation of line is three Expense y equals five And

00:17

the equation of line b is x plus three Why

00:20

equal six lines a and b are what Well the

00:26

dropdown thing here and gives us three options wants a

00:29

beer parallel perpendicular or the same Well we suppose they

00:33

could be the same line Although if that's true line

00:36

b has definitely had some work done Okay down to

00:40

business Figuring out one lines relation to another is all

00:43

about determining the slope And so we need to get

00:47

the slopes out of both lines and see how they

00:50

all shake out Both lines are written in the form

00:52

of a x plus B why equal c So we

00:55

can use the slope formula Slope equals negative A over

01:00

b to find what we need Well for line eh

01:03

We plug in three for a and negative one for

01:06

be Could get a slope of three Yeah because those

01:10

negative signs cancel out so that look the line be

01:14

We plug in one for a and three for b

01:18

to get a slope of negative one third like when

01:20

it's negative It slopes that way with positive it's like

01:23

that got it And because these two numbers are negative

01:27

reciprocal sze Well we can be sure we're looking at

01:30

a couple of perpendicular lines here We certainly hope those

01:33

two things work out and be ashamed They both reached 00:01:36.328 --> [endTime] their boiling point
