Equations of Perpendicular Lines

Today, we talked about perpendicular lines. We noted that the lines have to have opposite slopes (one line has a positive slope, while the other has a negative slope). We aksi noted that the products of the two slopes must be -1. Using the same process as we did to find equations of parallel lines, we did several examples in class, making sure everyone was able to complete each of the different steps of the process (identify the new slope, plug in the point of intersection, solve for b, and then write the new equation with the newly found values).

Tonight's Homework: Continue working on the practice test for Concept 7. It is due on Tuesday. Do all problems on both sides of the purple "Clicker Quiz" worksheet. In the home book, do page 203 (19 - 39, odd and 40).
