x1 y1 x2 y2
-1 4 2 5

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-%094++%29%2F%284-5%29=%28x-%28%09-1%29%29%2F%28-1-2%29


%28y-%09-4%29%2F%28-1%09%29=%28x%2B%091%29+%2F%28-3%09%29

%09-3%28y-%28-4+%29%29+=-1%28x-%28-1%29%09%29

-3 y- 12 = -1 x 1

-3 y= -1 x+ 13
/ -3
y= 1/ 3 x -13/ 3
