You need to add a new series, rather than just adding to the existing
series.
You may well get away with copying the 4 cells (E1:F2), then going to the
graph, & using Edit/ Paste Special, selecting new series, data in columns,
etc.

I did that, and the problem is it just interprets it as two more plot
points
rather than the endpoints of a continuous line graph.

Reference to your column with the 0 and 4000 cells (E1:E2) goes in the "X
values", and the reference to the column with the two Y values (F1:F2)
goes
in the "Y values" series. If you just click in the relevant series box
for
the new series, then go to the sheet with the data and select the
relevant
cells, it will put the cell references in automatically.

I'm not sure I completely understand.

I want my line to run from x = 0 to x = 4000. Therefore, my
corresponding
y
min and max would be:

min: y = 0.35592(0) + 0.1988939 = 0.1988939
max: y = 0.35592(4000) + 0.1988939 = 1423.8788939

Now, I did as you said and put these four values into my spreadsheet. I
have
the x min in cell E1, the y min in cell F1, the x max in cell E2, and
the
y
max in cell F2.

So, what exactly do I put under "X Values: " and "Y Values: " when I
add a
new Series?

Choose minimum and maximum X values for your new line & put them in
one
column. Calculate corresponding Y values from your equation and put
them
in
the next column. These then form the X and Y series to add as your
new
series to the chart.

I have a scatter plot chart that plots eight different coordinate
points
and
it looks really awesome. I also have done some calculations to my
data
and
have a linear equation of y = 0.35592x + 0.1988939. I want to plot
this
linear equation over the same chart as my scatter plot to show that
the
line
and the scatter plots are very closely related. How can I do this? I
assume
you right-click on the chart and click on "Source Data" and add
another
Series, but then what?
