the slope would be the change in Y over the change in X,
-7-1= -8, 3-(-1)= 4, -8/4 or -2 is the slope
You would pay $3.75
7.50÷2
The first one is < because if you have 5 part of 7, you have more parts than if you have 4 parts of 7, but it’s negative so it’s the opposite
So, 3.55 g of copper could be made from 4 g of copper oxide.
The formula for copper oxide to convert to copper is a chemical equation Cupric oxide, or copper (II) oxide, is an inorganic compound with the chemical formula CuO.
