Distance - Coordinate Plane

Front

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

Back

Distance = √((x2 - x1)² + (y2 - y1)²)

Front

What is the absolute value of a number?

Back

The absolute value of a number is its distance from zero on the number line, regardless of direction.

Front

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

Back

The distance is the difference in their x-coordinates.

Front

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

Back

The distance is the difference in their y-coordinates.

Front

What is the absolute value of -7?

Back

7

Front

If point A is at (3, 4) and point B is at (3, 10), what is the distance between them?

Back

6 units

Front

What is the distance between the points (0, 0) and (5, 0)?

Back

5 units

Front

What is the distance between the points (-3, -4) and (1, -4)?

Back

4 units

Front

What does it mean for two points to be equidistant from the origin?

Back

It means they are the same distance away from the point (0, 0) on the coordinate plane.

Front

How do you determine if a point lies on the x-axis?

Back

A point lies on the x-axis if its y-coordinate is 0.
