parellel and perpendicular lines

Front

What is the slope of parallel lines?

Back

The slopes of parallel lines are identical.

Front

What is the slope-intercept form of a linear equation?

Back

The slope-intercept form is represented as y = mx + b, where m is the slope and b is the y-intercept.

Front

What can be concluded about the lines represented by the equations -6x + y = 2 and 6x + y = 2?

Back

These lines are neither parallel nor perpendicular.

Front

What can be concluded about the lines represented by the equations y = 5/7x + 2 and y = 5/7x - 30?

Back

These lines are parallel.

Front

What is the relationship between the slopes of perpendicular lines?

Back

The slopes of perpendicular lines are opposite reciprocals.

Front

If two lines have the same slope, what can be said about their relationship?

Back

If two lines have the same slope, they are parallel.

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

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

What does it mean for two lines to be coincident?

Back

Two lines are coincident if they lie on top of each other, having the same slope and y-intercept.
