how do i graph in excel from a equation??
I'm trying to graph something as simple as y=30000x
is there any way to do so without having to have a series of number????

As that is a straight line you only need 2 points for your line. Decide
which you want the minimum & maximum x values for the graph to be, put those
in the the first column, and then put your equation for the corresponding y
values alongside in the second column. Select the cells containing the
data, insert chart, select XY, make sure that you allow it to treat the data
as being in columns, rather than rows.
