After students have learned how to graph lines and use point-slope formula and/or slope-intercept, this quiz is a great resource for combining them and using the same given line for determining lines that are both parallel and perpendicular to it. Requires knowledge of graphing, ordered pairs, slope, slope-intercept form, and the coordinate plane, and previous practice with point-slope formula. Includes ten total problems, answer key, and labeled coordinate plane graph paper. **Please note tha
