Distance in the Coordinate Plane

Front

What is the distance formula used to find the distance between two points (x1, y1) and (x2, y2) in the coordinate plane?

Back

Distance = √((x2 - x1)² + (y2 - y1)²)

Front

How do you find the distance between two points that have the same x-coordinate?

Back

Subtract the y-coordinates and take the absolute value.

Front

If two points have the same y-coordinate, what does that indicate about their position on the coordinate plane?

Back

They lie on a horizontal line.

Front

If two points have the same x-coordinate, what does that indicate about their position on the coordinate plane?

Back

They lie on a vertical line.

Front

How do you calculate the distance between points (x1, y1) and (x2, y2) if x1 = x2?

Back

Distance = |y2 - y1|.
