x1 y1 x2 y2
7 4 -5 9

The general equation of the line when co-ordinates of two points are given is

%28y-%09y1%29%2F%28%09y1-y2%29+=+%28x-x1%29%2F%28x1-x2%29




%28y%09-4++++++%09%29%2F%28%09-5++++++%09%29=%28x%09-7++++++%09%29+%2F%28%0912++++++%09%29

+%0912++++++%09%28y%2B%09-4++++++%09%29+=%09-5++++++%09%28x-%097++++++%09%29

12 y+ -48 = -5 x+ 35

12y+ 5x =83
5x+12y=83
