# (Solved): Step 1. Plot The Equality First i.e. An Equation Without Or Sign. Example: Step 2. Choose A T...

Step 1. Plot the **equality** first (i.e., an **equation** without < or > sign).

Example: ** **

Step 2. Choose a **trial point** so that a correct area (region) can be identified. The

most popular trial point is **(0, 0)**.

Step 3. Using the trial point, evaluate the **left-hand side** (LHS) expression and

determine if the trial point satisfies the inequality. If the trial point

satisfies the inequality, then the area which includes the trial point is the

**right** (correct) area.
