Thank you We sneak in and here's your shmoop du

00:05

jour brought to you by lines that passed through points

00:08

They never just stop and stay awhile Such rolling stones

00:12

a line passes through points to a negative a and

00:15

a for a bind the equation of the line And

00:19

here the fence line Okay well we should know by

00:25

now that if we're given a couple of points and

00:27

want to find the equation of line we're gonna have

00:29

to figure out the slope Yeah So let's hop onto

00:33

our little deal and take her for a spin All

00:35

right our slope formula is why two minus y one

00:38

over x to minus x one though And yeah this

00:43

is our y two and start y one r x

00:46

to x one Gonna plug everything in and we get

00:49

for a minus Negative a over a minus two eh

00:54

Two minus signs become positive leaving us with four a

00:57

plus a on the top or by day And we've

00:59

got a negative a on the bottom Well and a

01:03

cancels out from top and bottom And we're left with

01:07

negative five which is our slope Well great but we're

01:10

not quite finished We need the entire equation So time

01:12

to pull a little point Slope formula out of our

01:15

bag of tricks Second coordinate looks a little prettier No

01:18

negatives So let's use that one lugging these coordinates in

01:21

two point slope formula we get why Minus for a

01:26

equals negative five times The quantity x minus a distributing

01:31

that second part we get why money for a equals

01:34

minus five x plus five eh And then we can

01:37

add for eight of both sides Tow wind up with

01:39

why equals negative five x plus nine a which is

01:42
