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

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
