Module 9: Writing Linear Equations

Line t can be represented by the equation y = 3x − 5.

The equation of a line can be written in several forms. One of the forms that you may be most familiar with is slope-intercept form: y = mx + b, where m represents the slope of the line and b represents the y-intercept of the line. As you progress through this module, you will learn how to write the equation of a line in two additional forms: point-slope form and standard form. You will also investigate parallel and perpendicular lines, and learn how to write equations to represent these types of lines, as well.
