This is a video on plotting points on a
number line.  The question states, a
histogram will be drawn to display the
annual income that experienced registered
nurses make.  The boundaries of the bars
of the histogram are eighty one thousand,
one hundred and eight thousand, one
hundred and thirty five thousand, one
hundred and sixty two thousand, and one
hundred and eighty nine thousand.  Plot
these points on a number line.  In
order to plot points on a number line,
the first thing we need to do is draw a
number line.  That's just a horizontal
line, a bunch of dashes, and arrows on the
left and the right.  Here's my number
line.  The next thing I'm gonna notice
is that I don't want to count by ones.
That's for sure,
because we're going up into the hundred
and eighty nine thousand, it would take
forever.  Notice all of these numbers are
in thousands, so the first thing is I'm
going to label my number line in thousands.
That way, I don't have to put these
huge numbers.  The other thing is I
have 81, 108, all the way up to 189, so I'm
going to start at 80 in thousands, so eighty
thousand.  I'm going to end at 200 thousand.
That's a nice round number to finish off
on and I'm going to count by tens so I have 80, which is in thousands, so that's
80,000, 90,000, 100,000 and
then all the way up to 200,000.  Now
I just have to plot these points, so
let's start with 81,000.
here's 80.  81 is just a
little bit after that, so I'm going to plot
the 81 right there in thousands.
Then, I have 108,000.
Once again, here
is 100.  I'm going to go most of the way
to 110 and call that 108,000.  Then I have
135,000.  That
will be halfway between 130 and 140, so
there's 135.  Then
we have 162,000.  Here's 160 it's a little
bit past 160 just around there and I
plot 162.  Then finally, the last
number to plot is 189,000.  That's just before 190
,in thousands, so I
plot that point.  And there we have it.  I
have now plotted these five points on
the number line.  Thank you for
watching this video.
