What is the distance formula used to calculate the distance between two points (x1, y1) and (x2, y2)?

Back

Distance = √((x2 - x1)² + (y2 - y1)²)

What is the midpoint formula for finding the midpoint M between two points (x1, y1) and (x2, y2)?

Back

M = ((x1 + x2)/2, (y1 + y2)/2)

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they are in the same plane and do not intersect.
