If kx + 3y = 14 passes through the point (1,2k), find the value of k.
x = 1, y = 2k will be a solution of the equation kx + 3y = 14
Putting these values into the equation, we get
k + 6k = 14
7k = 14
k = 2
Find the value of k, if 2x + 3y = 13 passes through the point (2k,3k)
If kx - 2ky + 15 = 0 passes through the point (3,-1), then k = -3.
