TODAY IN ALGEBRA 2.0…  Learning Goal 1: 2.4 You will write equations of lines  Independent Practice-Assignment #4  Learning Goal 2: COE – If I only had a car Application Practice  Ch. 2 Quiz – Friday!

2.4 WRITING LINEAR EQUATIONS IN SLOPE-INTERCEPT FORM STARTING WITH A GRAPH! y-intercept

2.4 WRITING LINEAR EQUATIONS IN SLOPE-INTERCEPT FORM STARTING WITH A GRAPH! PRACTICE: Write an equation of the line shown.

2.4 CALCULATING THE Y-INTERCEPT: Given a point and slope. GIVEN!!!!!

2.4 CALCULATING THE Y-INTERCEPT: Given a point and slope. GIVEN!!!!!

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

2.4 PARALLEL AND PERPENDICULAR LINES Slope for y first!

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

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

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

2.4 CALCULATING SLOPE AND Y-INTERCEPT: Given 2 points. Write an equation of the line that passes through the given points:
