Complete ordered pairs for y=4x+12
(_,0), (3/4,_), (0,_), (3/4,_)

(0,3) for the third one if i'm doing it right...
(12,0) for the first
don't know about the other two 
in the ordered pair, the first number is always the x, the second is always the y
so for the first one, y = 0
0 = 4x + 12
12 = 4x
3 = x
so your first one is (3,0)
for the second:
y = 4(3/4) + 12
y = 3 + 12
y = 15, so the point is (3/4,15)
do the last one the same way, you should get (3/4,9)
btw, the third is (0,12)
