- complex variables

This is the problem;

Note that i am conversant with the above steps shown in the solution, having said that i realized that we could also borrow from the understanding of gradient and straight lines in finding the distance ##CD##... it follows that the equation of ##BA= -1.5x-0.5##, implying that the co ordinates of ##D(x,y) = (2-3, 4-3) = (-1,1)## and using the distance formula, it follows that;

##CD= √[(3)^2 + (1)^2]##= ##√10## as indicated...

any other approach guys...
