Step-by-step explanation:
Consider the provided information.
For the proportion method first set up the equation like this:
Perform the cross multiplication and then solve for the missing part.
For example:
Find 80 percentage of 10.
Step 1: Set up the equation.
Step 2: Perform the cross multiplication
Step 3: Solve for the missing part.
It’s on open dot because it doesn’t include the 4 and it shades all the numbers greater then 4 (so it goes to the right).
Yes to every single one except the 4/5

I don't know all 12, but I can tell you some.
1. Shade the side of the line that satisfies the inequality.
2. If the inequality sign has an "or equal to" line under it, make the line on the graph connected.
3. If the inequality sign does not have an "or equal to" line under it, make the line on the graph dashed.
4. Isolate y (or the variable that is being used), and keep it on the left side of the inequality.
