What is the graph of ?


Transcript

00:02

Okay More math drills for you A graphic time here

00:05

What is the graph of Why equals the three fifths

00:08

x minus two are what is the graph look like

00:16

Well the first observation that this question should inspire is

00:19

that the equation is in slope intercept form Remember that

00:23

guy He's probably annoyingly popular in your algebra class Yeah

00:26

raises hands all the time But just between you and

00:29

me nobody really likes him They just use them to

00:31

help with their homework Right You know i used to

00:33

be one of those people The general slope intercept equation

00:35

is y equals mx plus b were m's a slope

00:38

of the line and b is the y intercept of

00:40

the line So in this case the coefficient is Acts

00:43

35 right there So we're looking at a slope of

00:45

three fifth Well the constant term b is negative too

00:48

So the line crosses the y axis at negative too

00:52

Well to graph the line started the y intercept which

00:54

is the point You're only going to write there Then

00:56

we use the slope to find the next point of

00:58

line And slope is vertical change over horizontal change Right

01:02

rise overrun So we started zero negative too We moved

01:05

up three and over five Driving point Right there Five

01:09

one Well the on ly answer graph showing a line

01:11

that goes through both of these points of the first

01:13

one It's a so that's it That's the right answer 00:01:16.186 --> [endTime] Uh graphically yours
