Coordinate Graphing

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.

Quadrant I (x > 0, y > 0), Quadrant II (x < 0, y > 0), Quadrant III (x < 0, y < 0), Quadrant IV (x > 0, y < 0).

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.

The x-value is the first number in the ordered pair (x, y). For example, in (-4, 5), -4 is the x-value.

The y-value is the second number in the ordered pair (x, y). For example, in (2, 0), 0 is the y-value.

Quadrant I, because both x and y are positive.

Quadrant III, because both x and y are negative.

The origin is the point (0, 0) where the x-axis and y-axis intersect. It serves as the reference point for all other points on the plane.

A point is on the x-axis if its y-value is 0. For example, (5, 0) is on the x-axis.

A point is on the y-axis if its x-value is 0. For example, (0, -3) is on the y-axis.
