I'll need the value of z for that. [or it would be better if you repronounce the Q]
ok wait, let me check

if (6,k) is located on 3x + y - 2z = 0 , then it's a solution of that line's equation, we'll simply put the values of x and y in the equation.
3(6)-(k)-2z=0
18-k-2z=0
k=18-2z
by using the given options, you'll get various values of z, if z is a certain value and it's formed as a character, I prefer you checking it out once. once you get it, you can simply find the answer using the equation k=18-2z
Hope it helped.
