8-6.5 FLASHCARD 2023-2024 Slopes of Parallel and Perpendicular Lines

Front

What is the slope of a line in slope-intercept form?

Back

The slope (m) is the coefficient of x in the equation y = mx + b.

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they have the same slope and will never intersect.

Front

What does it mean for two lines to be perpendicular?

Back

Two lines are perpendicular if the product of their slopes is -1.

Front
