Since the line 'p' passes through the origin and has a slope of 3, its equation can be written as y = 3x.
Given that the points (x, 12) and (6, y) lie on the line 'p', we can substitute the coordinates into the equation to find their respective y-values:
For the point (x, 12): 12 = 3x x = 4
For the point (6, y): y = 3(6) y = 18
Now, we can calculate the value of x - 2y: x - 2y = 4 - 2(18) = 4 - 36 = -32
Therefore, the value of x - 2y is -32.
Hence, the correct answer is c: -32.
