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
