Question 913167: My 7th grader is stumped with his math homework and I don't know how to help him. Here is the problem: Write each interval as an inequality, then graph the solutions.
Problem 1: (infinity, -1) or (1, infinity)
Problem 2.: (0, infinity)
Thanks in advance for your help,
Tom

You can put this solution on YOUR website! Graphing the inequalities on a single number line is difficult to show using the algebra.com system, although easy to do ON PAPER.
Graphing the solutions depends on knowing what is the equation, inequality, or question. Not possible to graph these solutions without knowing what statement to be solved.
The problem 1 and 2 interval notation help is clearer.
Problem 1 is apparently written wrong. The first interval would better to be ( -infinity, -1). Interval notation shows left bound on the left and right bound on the right. The square bracket is to indicate inclusion of the number or value and the curved bracket, known as parenethesis, indicates the number or value to not be included.
Problem 1:
( -infinity, -1) or (1, infinity)
If using x as the variable for the line,
 OR 
Problem 2:
(0, infinity)
or you could say,
