Graphing on a 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 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), Quadrant IV (x > 0, y < 0).

Front

What does the point (0, 0) represent on a coordinate plane?

Back

The point (0, 0) is called the origin. It is the point where the x-axis and y-axis intersect.

Front

How do you identify the x-coordinate and y-coordinate in an ordered pair?

Back

In an ordered pair (x, y), 'x' is the x-coordinate (horizontal position) and 'y' is the y-coordinate (vertical position).

Front

What is the x-axis?

Back

The x-axis is the horizontal axis of the coordinate plane where the y-coordinate is 0.

Front

What is the y-axis?

Back

The y-axis is the vertical axis of the coordinate plane where the x-coordinate is 0.

Front

How many points can be represented in a coordinate plane?

Back

An infinite number of points can be represented in a coordinate plane, as it extends infinitely in all directions.

Front

What is the significance of the coordinates (x, 0)?

Back

Coordinates of the form (x, 0) lie on the x-axis.

Front

What is the significance of the coordinates (0, y)?

Back

Coordinates of the form (0, y) lie on the y-axis.

Front

What is the distance between the points (3, 2) and (3, -1)?

Back

The distance is 3 units, as they lie on the same vertical line (x = 3).
