Parallel and Perpendicular lines

Front

What are parallel lines?

Back

Lines that never intersect and have the same slope.

Front

What is the slope of parallel lines?

Back

The slopes of parallel lines are the same.

Front

What is the slope of perpendicular lines?

Back

The slopes of perpendicular lines are negative reciprocals of each other.

Front

How can you identify if two lines are parallel?

Back

If they have the same slope, they are parallel.

Front

What is the equation of a line parallel to y = -7x + 2?

Back

y = -7x - 1.

Front

What is the equation of a line parallel to y = 3/2x + 3?

Back

y = 3/2x - 2.

Front

What does it mean for two lines to be perpendicular?

Back

They intersect at a right angle (90 degrees).

Front

If the slope of one line is 2, what is the slope of a line perpendicular to it?

Back

The slope would be -1/2.

Front

What is the relationship between the slopes of two lines that are neither parallel nor perpendicular?

Back

Their slopes do not have a specific relationship.

Front

What is the general form of the equation of a line?

Back

y = mx + b, where m is the slope and b is the y-intercept.
