One More Time: Parallel and Perpendicular Lines

Performance on concept test 7 was either really good or rather poor. Students reflected on how they prepared for the test, and hopefully realized that not studying the material can influence the way they perform on the test. Students were reminded that the next test will be given on Friday, January 20th. It will cover linear equations: determining slope from two points, writing equations for parallel and perpendicular lines to a given line, and writing equations in standard form. We reviewed these processes again today.

Tonight's Homework: CME, page 371 (5 - 9). Although the directions state to write equations for parallel lines only, I would like you to do each problem twice--once following the book's directions, and a second time, finding the equation of the line perpendicular to that line going through the point listed.
