1. Parallel and Perpendicular Lines
Ch 5-6
Students will be able to determine whether lines are parallel, perpendicular, or neither.

Algebra 1 Foundations, pg 357

2. Ch 5-6
Students will be able to determine whether lines are parallel, perpendicular, or neither.
Two distinct lines in a coordinate plane either intersect or are parallel. Parallel lines are lines in the same plane that never intersect.
Focus Question
How do you use slope to find the relationship between two lines??
You can find a relationship between two lines by comparing their slopes. Parallel lines have the same slope. Perpendicular lines have slopes that are opposite reciprocals.

3. Ch 5-6
Students will be able to determine whether lines are parallel, perpendicular, or neither.
You can use the fact that the slopes of parallel lines are the same to write the equation of a line parallel to a given line.

4. Ch 5-6
Students will be able to determine whether lines are parallel, perpendicular, or neither.
You can also use slope to determine whether two lines are perpendicular. Perpendicular lines are lines that intersect to form right angles.
