# How could I use differentiation to calculate the minimum distance the line 4x – 5y + 8 = 0 is from the origin?

How could I use differentiation to calculate the minimum distance the line 4x – 5y + 8 = 0 is from the origin? The distance formula I know of is sqrt[(x2 - x1)^2 - (y2 - y1)^2] which does not seem to work in this case. Any assistance is greatly appreciated.
