Now we are dealing with two variables, and the graph of an inequality is the set of all ordered pairs (x, y) that satisfy the inequality. Typically, this will be represented by a half-plane.</p> <h2>Sketching an Inequality in Two Variables</h2> <ol> <li>Replace the inequality with an equal sign and sketch the resulting equation. Use a solid line if the equal to is included (&lt;= or &gt;=) and a dashed line of the inequality is
