Distance on the Coordinate Plane

Front

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

Back

Distance = √((x2 - x1)² + (y2 - y1)²)

Front

What is the distance between the points (10, -3) and (4, -3)?

Back

6 units

Front

What is the distance between the points (-4, 3) and (-4, -7)?

Back

10 units

Front

If the distance between two points is 7 units and one point is (5, -2), what could be the second point?

Back

(-2, -2) is one possible point.

Front

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

Back

3 units

Front

What is the distance between the points (-7, 8) and (2, 8)?

Back

9 units

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.

Front

How do you find the distance between two points that are vertically aligned?

Back

Subtract the y-coordinates and take the absolute value.

Front

How do you find the distance between two points that are horizontally aligned?

Back

Subtract the x-coordinates and take the absolute value.
