[6x-3y+10=0],[2x-y+9=0]

On comparing the ratios (a_(1))/(a_(2)),(b_(1))/(b_(2)) and (c_(1))/(c_(2)), and without drawing them,find out whether the lines representing the following pairs of the equations intersect at a point,are parallel or coincide: 8=0;quad 7x+6y-9=0 (ii) 9x+3y+12=0;quad 18x+6y+24=0 (iii) 6x-3y+10=0;quad 2x-y+9=0

Solve the system: x + y - 2z = 0, 2x - 3y + z = 0, 3x - 7y + 10z = 0, 6x - 9y + 10z = 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)

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 number of circles which touches the three lines 2x-3y+4=0 ,x+y-5=0 and 6x-9y+7=0 is

The graphs of the equations 6x-2y+9=0 and 3x-y+12=0 lines which are

2x+3y=5 6x+9y=10

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