Answer:
The line that represents the solution set of
is the second one.
Explanation:
If we want to find the line, we need to solve the inequality.
The inequality is

If we solve it in terms of x :



This means that the solution of the inequality
are all real numbers greater or equal to 3.
The line that represents
is the blue line in the second number line.
It is important to notice that
because in the second expression the number 3 is included.
In the second line the number ''3'' is included because there is a blue point in the number 3 instead of the first number line where in the number ''3'' the blue point is empty.
