How do you determine which part of the graph you have to shade in, when
solving systems of linear inequalities?
`
Solve the inequality for x or y, whichever is more convenient.
`
If you solve for x, and the inequality starts " x > " or "x > ", shade
the area to the RIGHT side of the line.
`
If you solve for x, and the inequality starts " x < " or "x < ", shade
the area to the LEFT side of the line.
`
If you solve for y, and the inequality starts " y > " or "y > ", shade
the area to the UPPER side of the line.
`
If you solve for y, and the inequality starts " y < " or "y < ", shade
the area to the LOWER side of the line.
