Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they have the same slope and will never intersect.

Front

What is the slope of the line represented by the equation y = -4x + 2?

Back

The slope of the line is -4.

Front

How do you determine the slope of a line that is parallel to another line?

Back

The slope of a parallel line is the same as the slope of the given line.
