right Okay so this question gives us the equation for

00:25

a line And we just need a pin down the

00:27

x and white intercepts or where our line crosses the

00:31

axes Easy peasy Where plenty of pins All right well

00:38

let's Start by plugging in zero for why and see

00:40

what x coordinate that gives us Well why equals two

00:45

x minus four would become zero equals two x minus

00:48

four We can add four to both sides to get

00:50

four equals two x and then divide both sides by

00:53

two to get the x equals two Cool So when

00:57

x is to y zero dot goes right here All

01:02

right now we'll do the same thing but plug in

01:04

zero for the ex Well why equals two x minus

01:07

four becomes y equals two times zero minus four Well

01:11

two times zero is zero so we get why equals

01:14

negative for our why intercept and has to be at

01:17

this point zero negative for right there and there we

01:23

go We're done yeah not sure immunity Use that many 00:01:27.353 --> [endTime] pins Save a few for crafting class
