of line Be classic question awesome and hear this Okay

lot information Here's let's Pick it apart We were given

two parallel lines Can be fine A has a slope

of five third So yeah it means be also slept

with five third parallel lines Always have the same slope

right Right now we're also told that line be passes

through the point Nine eight and we need to find

the equation of that line Sweet were awesome finding things

And you should just see this at easter Okay well

we have a point and we have a slope so

we're probably going to be asked to use the point

slope formula Like make sense Well plugging in our slope

of five thirds are y co ordinates of eight and

our x coordinate of nine We get why minus eight

equals five thirds times the quantity x minus nine Well

first things first let's distribute this stuff on the right

and we get y minus eight equals five thirds Acts

minus 45 thirds for this team both we take a

gander at our answer Choices will notice that these guys

were written in standard form We need to take our

equation and fiddle with it until we have the x

and y terms on the same side Well we'll start

by multiplying both sides by three to get rid of

that fraction and we have three Wide line is twenty

four equals five x minus forty five All subtract three

Why an ad forty five to both sides and we're

left with five x minus three y equals twenty one

answer See you can look but you don't huh girls
