• 3. A solution to a linear function is a point on the line.</li></li></ul><li>Example 1<br />
• 4. Graphing<br /><ul><li>The graph of a function is the set of ALL the points (x, y) that satisfy the equation.</li></li></ul><li>Graphing<br /><ul><li>The graph of a function is the set of ALL the points (x, y) that satisfy the equation.

For a linear function, all these points together create a line.</li></li></ul><li>Graphing<br /><ul><li>One way to graph a linear function is to create a table of values.</li></li></ul><li>Graphing<br /><ul><li>One way to graph a linear function is to create a table of values.</li></ul>Solve the equation for y.<br />
