Parallel, Perpendicular, neither practice

Front

What are the slopes of parallel lines?

Back

The slopes of parallel lines are the same.

Front

What are the slopes of perpendicular lines?

Back

The slopes of perpendicular lines are opposite reciprocals.

Front

If line AB has a slope of 4, what is the slope of a line parallel to it?

Back

The slope of a line parallel to AB is 4.

Front

If line AB has a slope of 4, what is the slope of a line perpendicular to it?

Back

The slope of a line perpendicular to AB is -1/4.

Front

What is the definition of parallel lines?

Back

Parallel lines are lines in a plane that never meet and have the same slope.

Front

What is the definition of perpendicular lines?

Back

Perpendicular lines are lines that intersect at a right angle (90 degrees) and have slopes that are opposite reciprocals.

Front

How do you determine if two lines are parallel using their slopes?

Back

Two lines are parallel if their slopes are equal.

Front

How do you determine if two lines are perpendicular using their slopes?

Back

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

Front

Given points A(2, 5) and B(6, 8), what is the slope of line AB?

Back

The slope of line AB is 3/4.

Front

Given points C(0, -2) and D(8, 4), what is the slope of line CD?

Back

The slope of line CD is 3/4.
