Parallel lines share the same slope, so the slope of the parallel line in this case must be
.
Point-slope form is
, where
is the slope and
is any known point on the line.
Plug in the values. 
Simplify and distribute. 
Subtract 1 from both sides. 
Answer:
Price per ounce is $0.062
Step-by-step explanation:
Here, we want to find the unit price in which this vase is price per ounce
Firstly, we need the total ounce value
1 pound = 16 ounce
so two pounds will be 2 * 16 = 32 ounces
So the total ounce value is 32 ounces + 8 ounce = 40 ounces
So 40 ounces = $2.48
price per ounce will be $2.48/40 = $0.062 per ounce
Equivalent systems = same line = infinite solutions
