x + y = 1
2x + 3y = 6
4x - y = 4

WITHOUT FINDING THE COORDS OF ITS VERTICES!!!

one way is take teh famiily of straight lines passing through the two lines of the triangle..

THen find the condition that they are perpendicular to the third line by seeing the slope..

In the same way find the equation of the second perpendicular..

SOlve them to get the equation of the Orthocenter
