Thank you We sneak in and here's your smoke du
- 00:05
jour brought to you by lines that don't touch Yeah
- 00:08
they're just huge germophobe right lines and beer Parallel line
- 00:11
a has a slope of five thirds and line be
- 00:15
passes through the point Nine eight What is the equation
Full Transcript
- 00:20
of line Be classic question awesome and hear this Okay
- 00:28
lot information Here's let's Pick it apart We were given
- 00:31
two parallel lines Can be fine A has a slope
- 00:35
of five third So yeah it means be also slept
- 00:37
with five third parallel lines Always have the same slope
- 00:41
right Right now we're also told that line be passes
- 00:44
through the point Nine eight and we need to find
- 00:46
the equation of that line Sweet were awesome finding things
- 00:50
And you should just see this at easter Okay well
- 00:53
we have a point and we have a slope so
- 00:55
we're probably going to be asked to use the point
- 00:56
slope formula Like make sense Well plugging in our slope
- 01:00
of five thirds are y co ordinates of eight and
- 01:02
our x coordinate of nine We get why minus eight
- 01:06
equals five thirds times the quantity x minus nine Well
- 01:10
first things first let's distribute this stuff on the right
- 01:13
and we get y minus eight equals five thirds Acts
- 01:17
minus 45 thirds for this team both we take a
- 01:21
gander at our answer Choices will notice that these guys
- 01:23
were written in standard form We need to take our
- 01:26
equation and fiddle with it until we have the x
- 01:28
and y terms on the same side Well we'll start
- 01:31
by multiplying both sides by three to get rid of
- 01:34
that fraction and we have three Wide line is twenty
- 01:36
four equals five x minus forty five All subtract three
- 01:39
Why an ad forty five to both sides and we're
- 01:42
left with five x minus three y equals twenty one
- 01:47
answer See you can look but you don't huh girls
