The line Ax + By + C = 0 cuts the x- axis at P and y - axis at Q. Find the co - ordinates of the ortho - centre of the Δ OPQ.
The points A, B and C are (4, 0), (2, 2) and (0, 6) respectively. Find the equations of AB and BC.
If AB cuts the y-axis at P and BC cuts the x-axis at Q, find the co-ordinates of P and Q.
