TODAY IN ALGEBRA… REVIEW: 5.1-5.3 Learning Goal: 5.5 Writing equations of Parallel and Perpendicular Lines STATs: Mid. Ch. 5 Test Independent Practice

2
REVIEW: LINEAR EQUATIONS SLOPE-INTERCEPT FORM:POINT-SLOPE FORM:

5
5.5 PARALLEL AND PERPENDICULAR LINES PARALLEL LINES:PERPENDICULAR LINES: PARALLEL LINES HAVE THE SAME SLOPE PERPENDICULAR LINES HAVE SLOPES THAT ARE NEGATIVE RECIPROCALS

6
5.5 PARALLEL AND PERPENDICULAR LINES Write slope as a fraction (Same slope) (flip the fraction and change the sign)

7
5.5 PARALLEL AND PERPENDICULAR LINES Slope for y first!

8
5.5 PARALLEL AND PERPENDICULAR LINES Slope for y first! PARALLEL LINES: line b & line c PERPENDICULAR LINES: line a & line b line a & line c

9
5.5 PARALLEL AND PERPENDICULAR LINES Slope for y first! PARALLEL LINES: line a & line b PERPENDICULAR LINES: line a & line c line b & line c

10
5.5 EQUATIONS OF PARALLEL LINES: Given a point and slope. SAME SLOPE!!!!!

11
5.5 EQNS OF PERPENDICULAR LINES: Given point and slope. NEGATIVE RECIPROCAL!!!!!

12
5.5 EQNS OF PERPENDICULAR LINES: Given point and slope. NEGATIVE RECIPROCAL!!!!!

13
HOW DID YOU “SHAPE” UP?? Results for ALL of my Algebra classes: GRADE NUMBER OF STUDENTS WHO TOOK THE MID CH.5 TEST (40 pts) 1 ST PERIOD6 TH PERIODTOTAL A/A-12416 B+/B/B-5510 C+/C/C-224 D+/D022 F71118 Average30.2326.4628.35
