Two points on a line have been measured by a CMM in the x$-$y plane. The point locations have the following coordinates: $(12\mathrm{.}257,2\mathrm{.}550)$ and $(3\mathrm{.}341,10\mathrm{.}294),$ where the units are inches and the coordinates have been corrected for probe radius. Find the equation for the line.
