Can you chart an equation (y=mx+b)?

[Guest]

I am trying to set up a graph in MS Excel where you can enter in the values
for X and B and it will graph the line, like a graphing caluclator would. Is
that possible?

Excel graphs points, not equations. For a straight line, you would only
need to calculate the first and last points on the line and plot them as
an "XY (Scatter)" chart with points connected by a line. Alternately,
Tushar Mehta has written an add-in for plotting functions

If the relationship is not necessarily linear, and you just want to hack out
a series without using an add-in, you can simply put a set of X values into
one column, then in the next column insert formulas that calculate the
appropriate Y values. Then make the plot with these two columns.
