  2. The symbol is greater than
  3. The symbol has "or equal to"
  4. You just guess

hintHint:

Note that, there are two types of lines- one is a solid straight red line and another one is a dotted red line. A solid straight line represents equality in an inequality whereas a dotted line indicates strict inequality.

The correct answer is: The symbol has "or equal to"


    Step 1 of 1:
    You can tell if an inequality will have a solid line by the symbol “or equal to.”
    The solid line indicates the inclusion of the points that are actually on the line. So, there is a case of equality coming into the picture.
    Final Answer:
    The right choice is-- c. The symbol has "or equal to"
