If the straight line `(3x+4y+5)+k(x+2y-3)=4` is parallel to x-axis then `k=`

The value of k such that the straight line (2x+3y+5)+k(x-7y+6)=0 is parallel to x-axis is

If the straight line (2x + 3y +4) +lambda (6x -y + 12) = 0 is parallel to y-axis then lambda=

What is the value of lambda if the straight line (2x + 3y +4) +lambda (6x - y + 12)=0 is parallel to y axis?

The value of k such that the straight line 3x+14y+7+k(5x+7y+6)=0 is perpendicular to x-axis is

Find the value of k if the lines (3x+4y+5)-k(x+y+3)=0 is (i) parallel to y-axis (ii) parallel to x-axis.

The value of k such that the line 3x+4y+5-k(x+y+3)=0 is parallel to y-axis is

The value of k such that the line 3x+4y+5-k(x+y+3)=0 is parallel to y-axis is
