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). Each point on the plane is defined by an ordered pair of numbers (x, y).

Front

What does an ordered pair represent?

Back

An ordered pair (x, y) represents a specific point on the coordinate plane, where 'x' is the horizontal position and 'y' is the vertical position.

Front

How do you calculate the distance between two points on a coordinate plane?

Back

The distance between two points (x1, y1) and (x2, y2) can be calculated using the distance formula: d = √((x2 - x1)² + (y2 - y1)²).

Front

What is the x-axis?

Back

The x-axis is the horizontal line on a coordinate plane where the y-coordinate is zero.

Front

What is the y-axis?

Back

The y-axis is the vertical line on a coordinate plane where the x-coordinate is zero.

Front

What does it mean if a point has a negative x-coordinate?

Back

A negative x-coordinate indicates that the point is located to the left of the origin (0, 0) on the coordinate plane.

Front

What does it mean if a point has a negative y-coordinate?

Back

A negative y-coordinate indicates that the point is located below the origin (0, 0) on the coordinate plane.

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.

Front

How do you determine the distance between two points with the same y-coordinate?

Back

If two points have the same y-coordinate, the distance between them is the absolute difference of their x-coordinates.
