Parallel & Perpendicular Flashcard

Front

What is the slope of parallel lines?

Back

The slopes of parallel lines are equal.

Front

What does 'm' represent in the equation y=mx+b?

Back

'm' represents the slope of the line.

Front

Are the following lines parallel, perpendicular, or neither? y = 2x + 1 and y = 2x - 4

Back

These lines are parallel.

Front

Given the equations y = 3x + 2 and y = 3x - 3, what can we say about these lines?

Back

These lines are parallel.

Front

What does 'b' represent in the equation y=mx+b?

Back

'b' represents the y-intercept of the line.

Front

If two lines have slopes that are opposite reciprocals, what is their relationship?

Back

They are perpendicular.

Front

What is the slope of a line that is vertical?

Back

The slope of a vertical line is undefined.

Front

What is the slope of a line that is horizontal?

Back

The slope of a horizontal line is 0.

Front

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

Back

If the slopes are equal, the lines are parallel.

Front

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

Back

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