11/19 Exit Flashcard Parallel, Perpendicular, or Neither

Front

What is the slope of parallel lines?

Back

The slopes of parallel lines are the same.

Front

What is the relationship between the slopes of perpendicular lines?

Back

The slopes of perpendicular lines are opposite reciprocals.

Front

Given the equations y=4x+1 and y=1/4x-50, are the lines parallel, perpendicular, or neither?

Back

Neither.

Front

Are the lines represented by the equations y = 3x – 7 and y = 3x + 1 parallel, perpendicular, or neither?

Back

Parallel.

Front

If two lines have slopes of -2/3 and 3/2, what is their relationship?

Back

They are perpendicular.

Front

What is the slope of a line in the equation y = mx + b?

Back

The slope is represented by 'm'.

Front

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

Back

If the slopes are equal, the lines are parallel.

Front

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

Back

If the product of their slopes is -1, the lines are perpendicular.

Front

What does it mean for two lines to be neither parallel nor perpendicular?

Back

It means their slopes are neither equal nor opposite reciprocals.

Front

What is the slope of the line represented by the equation y = 2x + 3?

Back

The slope is 2.
