If a pair of linear equations in two variables is inconsistent, then the lines represented by these equations are

The pair of equations $x=a$ and $y=b$ graphically represents lines which are

The value of $k$ for which the equations $3x-y+8=0$ and $6x-ky=-16$ represent coincident lines is

If the lines represented by $3x+2ky=2$ and $2x+5y+1=0$ are parallel, then the value of $k$ is

For which values of $p$, will the lines represented by the following pair of linear equations $3x-y-5= 0 \text{and} 6x-2y-p=0$ will be parallel?
