If there are 4 pens there will be 1 pencil, if there is 1 pencil there will be 4 pens
If the ratio is factored to a number, let's say 3, then there will be 12 pens for every 3 pencils
<u>3x + 2y = 4</u>
Here are a few different ways
to represent the same line:
2y = 4 - 3x
y = -1.5x + 2
5y = -7.5x + 10
3x = 4 - 2y
x = -2/3y + 4/3
