Exercise 2 Page 181

To determine the graph that matches the inequality, we first need to solve the inequality. We can do this by applying inverse operations to isolate the variable x on one side of the inequality.

Our solution of x>3 means that all possible values of x that are greater than 3 will satisfy the inequality. Notice that x cannot equal 3, so an open circle is shown here on the number line.

As can be seen, this number line corresponds with option B.
