SOLUTION: which of these equationss represent a vertical line? i 2x - 3y = 6 ii 2x + 3y = 6 iii 2x = 6 iv 3y = 6 I think the answer is "iv" but that's cause i worked it out in my hea

Question 115842: which of these equationss represent a vertical line?
i 2x - 3y = 6
ii 2x + 3y = 6
iii 2x = 6
iv 3y = 6
I think the answer is "iv" but that's cause i worked it out in my head. y=2. But i am not too sure how to go about proving the first 2 wrong???
Thanks

2x=6
x=6/2
x=3 is a verticle line.
3y=6
y=6/3
y=2 is an horizontal line.
