Module 9: Writing Linear Equations

As you progressed through this module you explored several concepts involving linear equations. You learned how to write the equation of a line when given information about the line:

• the graph of the line,
• the slope and a point on the line, or
• two points on the line.

You also investigated horizontal and vertical lines, and parallel and perpendicular lines and learned how to write equations to represent these types of lines, as well.
