How do I show slope of a trendline on a plot ????
 

I have a simple plot with two points only, and added a trendline which fits
with the plotted line. I really need to show the slope of the trend line on
the plot. But I dont want to show the equation or anything else.

I am using a plot which should calculated and plot by itself with the change
of inputs in the table(somewhere in the page), and need to show that slope
value on the plot too.

I can calculate slope in a cell somewhere on the sheet. Is there any way to
show the value (calculated somwhere on the sheet) on the plot beside my
plotted line.

Either way would work. But I prefer to do it from the trendline.
please help.
