Algebra I Recipe: Solving and Graphing Systems of Inequalities
Steps:
  1. Graph all the inequalities on the same coordinate plane line as in Sec. 6.5.
  2. Determine where the shading overlaps and darken in that area darker.
  3. The solutions are where the shading overlaps.
ExamplesExamples:
y ≥ -3x - 1
y < x + 2

x ≥ 0
y ≥ 0
4x - 3y ≤ 4

2x + y ≥ -4
x - 2y < 4

y < 2
x ≥ -1
y > x - 2

x ≥ 0
y > 2x - 1
y ≤ 2x + 3
