Transcript

00:00

Thank you We sneak in and here's your smoke to

00:05

ensure brought to you by linear functions We get so

00:08

excited about them It's verging on linsanity all right fx

00:13

is a linear function that passes through the points Negative

00:17

one zero zero two The equation of fx's two x

00:21

plus what What's this question asking Well we're told that

00:28

we're dealing with a linear function and were given a

00:31

couple of points the line would pass through Now all

00:34

we need to do is figure out the equation The

00:36

important thing you recognize here is that we'll need to

00:38

put this equation in slope intercept How do we know

00:42

that any time a linear equation is written with fx

00:45

or why isolated on one side it's a pretty good

00:48

clue okay by us We know slope intercept form like

00:52

sola neuville vector field Or the back of our hands

00:58

So we know right off the bat with line hits

01:00

the y axis because we're given the point zero two

01:03

which is right here up to from zero zero in

01:06

the origin if we plug in zero for acts into

01:08

for why or death of Acts are equation becomes 2

01:12

equals two times zero plus something well two times zero

01:17

is just zero Our equation is really two equals blank

01:22

and as far as we know the only thing to

01:23

khun equal is d'oh and that's What we'll put in

01:26

the blank by the way sorry about scaring you earlier

01:29

Don't worry it'll be a few years before you have 00:01:31.509 --> [endTime] to worry about solar vector Good luck with those
