Slope of Parallel and Perpendicular Lines

Front

What is the slope of parallel lines?

Back

The slopes of parallel lines are the same.

Front

What is the slope of a line that is parallel to a line with slope m = 3/4?

Back

The slope is 3/4.

Front

What type of slopes do parallel lines have?

Back

Parallel lines have equal slopes.

Front

What is the slope of a line perpendicular to a line with slope 5?

Back

The slope is -1/5.

Front

Which lines are perpendicular?

Back

Two lines are perpendicular if their slopes are opposite reciprocals.

Front

Define slope in the context of a line.

Back

Slope is a measure of the steepness of a line, calculated as the rise over run.

Front

What is the relationship between the slopes of perpendicular lines?

Back

The slopes of perpendicular lines are opposite reciprocals.

Front

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

Back

The slope is -1/2.

Front

How do you find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What does a slope of 0 indicate about a line?

Back

A slope of 0 indicates a horizontal line.
