a) L: 3x-4y=12
M: 6x-8y= 9

b) L: 3x+4y=2
M: x-2y=1

c) L: 2x+3y=9
M: y= -2/3x + 3

So...you've thought about the fact that lines with the same slope are parallel, lines with the same slope and the same y-intercept are coincident (the same line), and lines with different slopes intersect.

And you've found the slope for each line. Then what?

If you show us no work, there's no way we can see where you need help.
