Coordinate Planes

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 pairs of numbers called coordinates.

Front

What are coordinates?

Back

Coordinates are a pair of numbers that define the position of a point on a coordinate plane. The first number represents the horizontal position (x-coordinate), and the second number represents the vertical position (y-coordinate).

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 the four quadrants of a coordinate plane?

Back

The four quadrants are: Quadrant I (x > 0, y > 0), Quadrant II (x < 0, y > 0), Quadrant III (x < 0, y < 0), and Quadrant IV (x > 0, y < 0).

Front

What is the x-axis?

Back

The x-axis is the horizontal line on a coordinate plane where the y-coordinate is zero. It runs left to right.

Front

What is the y-axis?

Back

The y-axis is the vertical line on a coordinate plane where the x-coordinate is zero. It runs up and down.

Front

How do you plot a point on a coordinate plane?

Back

To plot a point, start at the origin (0,0). Move horizontally to the x-coordinate and then vertically to the y-coordinate.

Front

What are positive and negative coordinates?

Back

Positive coordinates are found in Quadrants I and IV, where x or y values are greater than zero. Negative coordinates are found in Quadrants II and III, where x or y values are less than zero.

Front

What is 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: √((x2 - x1)² + (y2 - y1)²).

What is a line of symmetry in a coordinate plane?

Back

A line of symmetry is a line that divides a shape into two identical halves that are mirror images of each other.
