Houston i have a problem here, the maths does not add up in the plots, if OP is the output frequency, the equation of the straight line would be:
OP = -nRF + mLO
-n is the slope , mLo is the y-intercept.or input RF = 0 hz and m = 1, OP = mLO=3.6GHz. In the graph, the lines all intercept at 6GHz, I am confused now and need to go away to do some exercises to clear my head.

Ok, the muppet overlooked the LO slider. Now the numbers add up.
This old paper based web works similarly except they non-dimensionalize by dividing the output OP and RF frequencies by LO:

OP = mLO + nRF
Op/LO = n RF/LO + m
n = slope
m = y-intercept
