Coordinate Plane

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 (x, y).

Front

What are the coordinates of a point?

Back

Coordinates of a point are a pair of numbers (x, y) that define its position on the coordinate plane, where 'x' represents the horizontal position and 'y' represents the vertical position.

Front

What is the x-axis?

Back

The x-axis is the horizontal number line in the coordinate plane, where the value of 'y' is zero.

Front

What is the y-axis?

Back

The y-axis is the vertical number line in the coordinate plane, where the value of 'x' is zero.

Front

What is the origin in a coordinate plane?

Back

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

Front

What are quadrants in a coordinate plane?

Back

Quadrants are the four sections of the coordinate plane created by the x-axis and y-axis. They are labeled as Quadrant I, II, III, and IV.

Front

How do you find the distance between two points (A and B) on a coordinate plane?

Back

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

Front

What are positive and negative coordinates?

Back

Positive coordinates are found in Quadrants I and IV, where x or y values are positive. Negative coordinates are found in Quadrants II and III, where x or y values are negative.

Front

What is the significance of the ordered pair (0, 0)?

Back

The ordered pair (0, 0) represents the origin, the starting point for measuring distances and locations on the coordinate plane.

Front

What does it mean for a point to be on the x-axis?

Back

A point is on the x-axis if its y-coordinate is 0, meaning it lies horizontally along the x-axis.
