we have
6x+3y=12 -----> line p
Find the slope
3y=-6x+12
y=-2x+4
m=-2
-4x=2y-2 -----> line Q
2y=-4x+2
y=-2x+1
m=-2
therefore
the lines are parallel because their slopes are equal

Answer:
The larger ham is the better buy.
Step-by-step explanation:
In order to determine the better buy, divide both of the prices by their weight to get the price per pound of ham.
5.70/3 = 1.90 per lb
8.75/5 = 1.75 per lb
Therefore the 5 pound of ham is a better buy.
1. -56
2. say you owe someone 84$, so that's 84$ you don't have, then you give that person 28$. now you only owe them 56$.
