I created a graph and then a trendline to get the slope of the line and then
used m to determine another value which would be constant for all data in
that data set (least squares regression). HOWEVER, I also have to find the
mean and st. dev. for this data. I know the mean is obviously the same at
the constant,

What you "know" is not true. The mean is generally not equal to the y
intercept.

but what is the standard deviation

See the AVERAGE and STDEV functions.
