Make a graph (chart), draw a straight line on the graph. So what's the
slope
and the intercept? An option to display the linear equation would quickly
reveal both.

Excel cells should be able to directly link to precise values of the
coefficients of the equations displayed in a graph. I can't say how many
times I've modeled a best fit only to find that a coefficient changed when
my
original data changed or that a manual entered coefficient wasn't precise
enough and yielded a bad fit equation.
