A S5.5 Perpendicular and Parallel Lines.notebook 1 December 19, 2016 Sep 75:46 AM Today's Lesson : Let us remember we are in the holy presence of God * Sect 5.5 Equations of Perpendicular (and Parallel) Lines * Mid Ch 5 quiz , Dec 22nd * I'll pass back test after notes Instructions : Prayer person to podium * We will Grade Assign #46 and #47 after our notes today * Pick up a "Discovering slopes of perpendicular lines" notes sheet (on table by the door) and begin working on it (10 minutes) From the pairs of lines and their slopes, fill in the blank: 1) If the slope of one line is negative, the slope of the other _______________________. 2) Slopes perpendicular line pairs have slopes that are __________________________ ____________________________. 3) If pairs of lines are perpendicular and one line has m= 2 /3 , what is the slope of 2nd line? m=_____ Aug 2912:04 AM Before working the problems lets try to visualize what is being asked. Write the equation of the line that goes through the point (4, 3) (ex 1) that is parallel to y=2x1 (ex 2) that is perpendicular to the line y=2x1 Section 5.5 Equations of Parallel and Perpendicular Lines I can write the equation of a line parallel or particular to a given line through a given point. Aug 2912:04 AM Now lets answer it (Homework example) Write the equation of the line that goes through the point (4, 3) (ex 1) that is parallel to y=2x1 I can write the equation of a line parallel or particular to a given line through a given point. Aug 2912:04 AM Write the equation of the line that goes through the point (4, 3) (ex 2) that is perpendicular to the line y=2x1 I can write the equation of a line parallel or particular to a given line through a given point. Aug 2912:04 AM Another Homework example: (ex 3) Write the equation of the line that goes through the point (12, 8) and is perpendicular to the line y= 3 / 4 x+15 Section 5.5 Equations of Parallel and Perpendicular Lines I can write the equation of a line parallel or particular to a given line through a given point. (ex 4) Write the equation of the line that goes through the point (6,5) and is parallel to the line 8x2y=11 Aug 2912:04 AM Assign #47 Answers : out of 6, ex 5/6 2) slopeintercept form 12) 3x+y=13 14) 4x+y=32 16) 1 / 6 x+y=9 18) x+y=7 20) 4x+y=3
