1. { 2.4 Writing Equations of Lines

2.  Slope-Intercept Form:  Standard Form: Forms of Lines

3.  Graph line in slope- intercept form: **Begin with y-intercept—b **Move slope—3 points **Connect to make the line Graphing Lines

4. Write equation of the line from: 1. Graph 2. Slope and y-intercept 3. Slope and a point 4. Two points 5. Parallel to a given line (same slopes) 6. Perpendicular to a given line (opposite reciprocal slopes) Writing Equations of Lines
