Distance Formula Review

What is the Distance Formula?

Back

The Distance Formula is used to determine the distance between two points in a coordinate plane, given by the formula: d = √((x2 - x1)² + (y2 - y1)²).

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

Back

To find the distance between two points on a number line, subtract the smaller number from the larger number: Distance = |x2 - x1|.

What is the distance between -7 and 9 on a number line?

Back

16 units.

Front

What is the y-axis in a coordinate plane?

Back

The y-axis is the vertical line that runs up and down on a coordinate plane.

Front

What is the x-axis in a coordinate plane?

Back

The x-axis is the horizontal line that runs side to side on a coordinate plane.

Front

What are coordinates?

Back

Coordinates are a set of values that show an exact position on a coordinate plane, typically written as (x, y).

What is the distance between the points (3, 4) and (3, 0)?

Back

4 units.

What is the distance between the points (1, 2) and (4, 6)?

Back

5 units.

Front

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

Back

If two points have the same x-coordinate, they lie on a vertical line.

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

Back

If two points have the same y-coordinate, they lie on a horizontal line.
