On this question it is asked you to describe the solution of an inequality represented by the given graph. First of all you may know that the meaning of the phrases "greater than" and "less than" depends on the direction of the line graphed and the possibles solutions are also associated to whether or not the circle is close or open.
When you look at the line plot you can see, that the point is open meaning that 2.5 is not a possible answer for the equation. Also, the line goes to the right meaning that the values for the possible solutions have to greater than 2.5. In other words the solution for the graphed inequality are the numbers greater than 2.5 but 2.5 is not part of the solution.
The correct answer is all real numbers greater than 2.5.
