Front

What are parallel lines?

Back

Lines in a plane that never meet and are always the same distance apart.

Front

What are perpendicular lines?

Back

Lines that intersect at a right angle (90 degrees).

Front

What does the variable 'm' represent in the slope-intercept form of a line?

Back

The slope of the line.

Front

What does the variable 'b' represent in the slope-intercept form of a line?

Back

Front

What is the relationship between the slopes of parallel lines?

Back

Parallel lines have the same slope.

Front

What is the relationship between the slopes of perpendicular lines?
