If two sides of a triangle are represented by `2x-3y+4=0 and 3x+2y-3=0`, then its orthocentre lies on the line : (A) `x-y+ 8/15 = 0` (B) `3x-2y+1=0` (C) `9x-y+9/13 = 0` (D) `4x+3y+5/13=0`

The region represented by 2x+3y-5ge0 and 4x-3y+2ge0 is

Two sides of a triangle are 2x -y =0 and x + y = 3. If its centroid is (2, 3) its third side is (A) x + 5y – 9 = 0 (B) 5x – Y – 9 = 0 (C) x + 5y + 9 = 0 D) 5x – y + 9 = 0

If the equations of three sides of a triangle are x+y=1, 3x + 5y = 2 and x - y = 0 then the orthocentre of the triangle lies on the line/lines

Find the orthocenter of the triangle formed by the lines x + 2y = 0, 4x + 3y - 5 =0, 3x + y = 0 .

3x - 2y + 1 = 0 and 2x - y = 0 are the equation of the sides AB and AD of the parallelogram ABCD and the equation of a diagonal of the parallelogram is 5x - 3y - 1 = 0 . The equation of the other diagonal of the parallelogram is : (A) x-y+1=0 (B) x-y-1=0 (C) 3x+5y+13=0 (D) 3x+5y=13

Find the area of triangle formed by the lines: x+y-6=0,x-3y-2=0 and 5x-3y+2=0

If (2, -2),(-1,2), (3,5) are the vertices of a triangle then the equation of the side not passing through (2,-2) is (A) x + 2y +1 = 0 (B) 2x - y- 4= 0 (C) X-3y -3= 0 (D) 3x – 4y + 11 = 0
