Front

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

Back

Front

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

Back

3 units.

Front

What is the distance between points (5, -2.3) and (5, 4.9)?

Back

7.2 units.

Front

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

Back

Subtract the y-coordinates and take the absolute value.

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

Back

10 units.

Front

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

Back

6 units.

Front

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

Back

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

Front

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

Back

They lie on a vertical line.

Front

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

Back

They lie on a horizontal line.

Front

What is the significance of the absolute value in distance calculations?

Back

It ensures that distance is always a non-negative value.
