Graphing from point/slope Parallel & Perpendicular Essential Question: Describe the difference in slopes of two lines that are perpendicular to each other.

Review Find the slope of the line passing through… (4,6)and(8,9) x y 34 Essential Question: Describe the difference in slopes of two lines that are perpendicular to each other.

Vocabulary Parallel Lines: Two lines in the same plane, that have THE SAME EXACT SLOPE. Plane: A flat surface that extends in all directions. Perpendicular Lines: Two lines in the same plane, that have OPPOSITE RECIPROCAL SLOPES. In other words, they criss-cross each other perfectly at 90 degree angles. Essential Question: Describe the difference in slopes of two lines that are perpendicular to each other.
