1. 2.4 Lines

2. Slope Find the slope of the line passing through the given points.

3. Slope (+) Slope (-) Slope Zero Slope No Slope

4. Graphing Linear Equations Graph a line given a point and the slope

5. General Form X and Y must be on the same side A and B may not contain any fractions A must always be positive

6. Point slope Find the equation of a line in general form given a point and a slope.

7. Find the equation of a line in general form given two points. Point slope

8. Slope – Intercept Find the slope and y-intercept of each equation and graph.

9. 2.5 Parallel and Perpendicular Lines

10. Parallel Lines Two non-vertical lines are parallel if and only if their slopes are equal and they have different y-intercepts.

11. Two non-vertical lines are perpendicular if and only if the product of their slopes is – 1. Perpendicular Lines

12. Determine if the lines are parallel, perpendicular, or neither.
