`x-3y-3=0`; `3x-9y-2=0`

Which of the following pairs of linear equations has unique solution, no solution, or infinitely many solution, no solution, or infinitely many solutions. In case there is a unique solution, find it by using cross multiplication method. x-3y-3=0 and 3x-9y-2=0

The area of the parallelogram formed by the lines 2x-3y+a=0, 3x-2y-a=0, 2x-3y+3a=0 and 3x-2y-2a=0 in square units , is

Solve the following system of homogeneous equations. 3x+2y+7z=0,4x-3y-2z=0, 5x+9y+23z=0

2x-y-5=0; x+3y-9=0

If y-3=0,x-3y+9=0 and 3x-2y+1=0x+y-3=0,x-3y+9=0 and 3x-2y+1=0 are sides of triangle then area of triangle.

Classify the following pairs of lines as coincident,parallel or intersecting: x+2y-3=0 and -3x-6y+9=0x+2y+1=0 and 2x-4y+3=03x-2y+5=0 and 2x+y-9=0

The area of the parallelogram formed by lines 2x-y+3=0, 3x+4y-6=0,2x-y+9=0, 3x+4y+4=0 is (in sq units)

If one of the diagonals of a square is along the line x=2y and one of its vertices is (3, 0), then its sides through this vertex are given by the equations (A) y-3x+9=0, 3y+x-3=0 (B) y+3x+9=0, 3y+x-3=0 (C) y-3x+9=0, 3y-x+3=0 (D) y-3x+9=0, 3y+x+9=0
