The point ($$-$$4, 5) is the vertex of a square and one of its diagonals is 7x $$-$$ y + 8 = 0. The equation of the other diagonal is

The straight line 3x + y = 9 divides the line segment joining the points (1, 3) and (2, 7) in the ratio

If the sum of distances from a point P on two mutually perpendicular straight lines is 1 unit, then the locus of P is a/an

If the three points (3q, 0) (0, 3p) and (1, 1) are collinear then which one is true?
