Graphing Inequalities

  • When  a circle is closed on a graph (as shown on top) and goes to the left, it means that the whole number (11) is greater than or equal to the variable (x) .
  • If the circle is open though (as shown on bottom) and points to the right, the variable (x) is greater than the whole number (11).

Graph these equations

x ≤ 4                         x > 6                         x ≤ 16                         x > 13
