Coordinate plane/Distance

Front

What is a coordinate plane?

Back

A coordinate plane is a two-dimensional surface formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis). It is used to locate points using ordered pairs.

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to locate a point on the coordinate plane, written in the form (x, y).

Front

What does the x-axis represent?

Back

The x-axis is the horizontal line on a coordinate plane, representing the value of the x-coordinate in an ordered pair.

Front

What does the y-axis represent?

Back

The y-axis is the vertical line on a coordinate plane, representing the value of the y-coordinate in an ordered pair.

Front

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

Back

To find the distance between two points on the same vertical line, subtract the y-coordinates and take the absolute value.

Front

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

Back

To find the distance between two points on the same horizontal line, subtract the x-coordinates and take the absolute value.

Front

What is the distance between the points (2, 3) and (2, 7)?

Back

The distance is 4 units.

Front

What is the distance between the points (5, -1) and (5, 2)?

Back

The distance is 3 units.

Front

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

Back

The distance formula is: Distance = √((x2 - x1)² + (y2 - y1)²).

Front

What is the origin in a coordinate plane?

Back

The origin is the point (0, 0) where the x-axis and y-axis intersect.
