Distance on the coordinate plane

Front

What is the distance formula for two points (x1, y1) and (x2, y2)?

Back

Distance = √((x2 - x1)² + (y2 - y1)²)

Front

What is the distance between points (3, -5) and (3, -8)?

Back

3 units

Front

How do you find the distance between two points on a horizontal line?

Back

Subtract the x-coordinates: |x2 - x1|.

Front

How do you find the distance between two points on a vertical line?

Back

Subtract the y-coordinates: |y2 - y1|.

Front

Front

What does it mean if two points have the same x-coordinate?

Back

They are vertically aligned on the coordinate plane.

Front

What does it mean if two points have the same y-coordinate?

Back

They are horizontally aligned on the coordinate plane.
