Least Common Multiple (LCM) of 4 and 8 is 8. 4 is 2 x 2, while 8 is 2 x 2 x 2. We take the first two that's shared, second two's that shared, and third two that's note. We have three twos, or 2 x 2 x 2 = 8. So the LCM of 4 and 8 is 8.

Step-by-step explanation:
(3, -2) and (9, 0)
x-3(-2)=9
x+6= 9
x=3
9-3y=9
-3y=0
y=0
