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

Sure brought to you by missing lines It can make
- 00:10
for quite an awkward night of theater all rights like
- 00:13
the x and y intercepts of the line Why equals
- 00:16
two x minus four on the graph below This thing

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
