A coordinate grid is a two-dimensional plane formed by the intersection of a horizontal line called the x-axis and a vertical line called the y-axis.

The x-coordinate is the first number in an ordered pair that determines the movement left or right from the origin on a coordinate grid.

The y-coordinate is the second number in an ordered pair that determines the movement up or down from the origin on a coordinate grid.

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

Start at the origin (0, 0), move 2 units to the right (x-coordinate), and then move 5 units up (y-coordinate).

The y-axis is the vertical number line in a coordinate grid.

The x-axis is the horizontal number line in a coordinate grid.

It means that the x-axis and y-axis intersect at a right angle (90 degrees) at the origin.

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

A coordinate grid is used to visually represent points, lines, and shapes in a two-dimensional space.
