Graphing on a Coordinate Grid

Front

What is a coordinate grid?

Back

A coordinate grid is a two-dimensional plane formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis), 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 a coordinate grid, 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 line in a coordinate grid where the y-coordinate is zero (0). Points on this line have the form (x, 0).

Front

What is the y-axis?

Back

The y-axis is the vertical line in a coordinate grid where the x-coordinate is zero (0). Points on this line have the form (0, y).

Front

How many quadrants are in a coordinate plane?

Back

There are 4 quadrants in a coordinate plane, each representing a different combination of positive and negative values for x and y.

Front

What is the origin in a coordinate grid?

Back

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

Front

What are the coordinates of the point located at (2, -2)?

Back

The coordinates (2, -2) indicate a point that is 2 units to the right of the origin and 2 units down.

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 zero, meaning it lies horizontally along the x-axis.

Front

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

Back

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

Front

What are the coordinates of the point located at (-2, 2)?

Back

The coordinates (-2, 2) indicate a point that is 2 units to the left of the origin and 2 units up.
