`3/x-1/y+9=0` `2/x+3/y=5,(!=0,y!=0)`

( 3 ) /(x) - (1 ) /( y) + 9 = 0 , (2)/(x) + ( 3)/( y) = 5 ( x ne 0 , y ne 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.

The straight lines x+2y-9=0, 3x+5y-5=0, ax+by+1=0 are concurrent if the line 22x-35y+1=0 passes through the point

Using the method of integration, find the area of the region bounded by the lines : 3x-2y+1=0, 2x+3y-21=0 and x-5y+9=0.

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

2(2x+y+5)+3(x-3y-1)=0 2x-3y+1=0

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

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
