2. Bell Work1/13/15 Write in slope-intercept form the equation of the line passing through the given point and PARALLEL to the given line.

3. Yesterday’s Homework 1.Any questions? 2.Please pass your homework to the front. Make sure the correct heading is on your paper. Is your NAME on your paper? Make sure the homework is 100% complete. Incomplete work will NOT be accepted.

4. Slopes of Parallel and Perpendicular Lines (perp.) 5/19/2015 Heading TSWBAT: write an equation in slope- intercept form given a point and a perpendicular line. Students understand the concepts of parallel lines and perpendicular lines and how those slopes are related. Students are able to find the equation of a line perpendicular to a given line that passes through a given point.

5. Notes Graph the lines. Ex. b = beginning m = move = Two lines that intersect at right angles. Perpendicular Lines Their slopes are OPPOSITE RECIPROCALS.

6. Notes Find the opposite reciprocal. Ex. Now you try. Ex.

7. Notes Determine if the two lines are PERPENDICULAR. Ex. Yes Ex. No Ex. No Ex. Yes Now you try.

8. Notes Write in slope-intercept form the equation of the line passing through the given point and PERPENDICULAR to the given line. Ex. Label your points. What is our slope? Ex. Now you try.

9. Notes Write in slope-intercept form the equation of the line passing through the given point and PERPENDICULAR to the given line. Ex. Label your points. What is our slope? Ex. Now you try.

10. Summary To find the equation of a ____ perpendicular to another line and that goes through a specific point you first just take oppoiste __________ of the slope from the given line. With that slope and the given point plug it into the point-______ formula and solve for y. line reciprocal slope
