AThe answer is B because if you plug in the two intercepts (0,-3), and (6,0) it is the only equation that works for both.
B) The easiest way is to simplify the equation (6x-2y = 12 => 3x-y=6) and then to plug in the intercepts (0,-6) and (2,0) or check the slope. Either way the answer is A.
Hope this helps!
