Given the four lines with the equations `x+2y -3 = 0,3x+4y-7=0, 2x +3y - 4 = 0, 4x+5y -6 =0, then

Answer» Here, we are given 4 lines
`x+2y-3=0`
`3x+4y-7=0`
`2x+3y-4=0`
`4x+5y-6=0`
If, we subtract twice of third equation from fourth equation, we get
`y=2` and putting it in any of the equation, we get `x=-1`.
If we put these value in first line equation,
`-1+2(2)-3=0` that is ` true`.
If we put these value in second line equation,
`2(-1)+3(2)-4=0` that is not true.
That means three lines are intersecting at point(-1,2), but the fourth one is not that concludes
They are not concurrent and they are not forming quardilateral.So, option `C` None of these is the correct option.
