Find the value of 'k' for which the pair of equations 2x - ky + 3 = 0. 4x + 6y - 5 = 0 represent parallel lines.

The value of k for which the pair of linear equations 4x + 6y -1= 0 and 2x + ky -7=0 represents parallel lines is

The value of k for which the pair of linear equations 7x+ 3y - 5 =0 and 14x +ky -2=0 represent parallel line is ………………

For what value of 'k'. The pair of equations 3x + 4y + 2 = 0 and 9x + 12y + k = 0 represents coincident lines.

The values of k for which lines kx + 2y + 2 = 0, 2x + ky + 3 = 0, 3x + 3y + k = 0 are concurrent are

9x^(2) +2hxy +4y^(2) +6x +2fy - 3 = 0 represents two parallel lines. Then

Find the values of k for which the line (k - 3) x - (4 - k^(2)) y +k^(2) - 7k + 6 = 0 is (a) Parallel to the x-axis, (b) Parallel to the y-axis, (c) Passing through the origin.

Find the value of a for which the straight lines x+y-4=0,3x+2=0 and x-y+3a=0 are concurrent.

If the equation kx^(2) – 2xy - y^(2)– 2x + 2y = 0 represents a pair of lines, then k =
