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 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).

What are the coordinates of a point?

Back

Coordinates of a point are expressed as an ordered pair (x, y), where 'x' represents the horizontal position and 'y' represents the vertical position on the coordinate plane.

Front

What does Quadrant I represent?

Back

Quadrant I represents the area where both x and y coordinates are positive.

Front

What does Quadrant IV represent?

Back

Quadrant IV represents the area where x coordinates are positive and y coordinates are negative.

Front

How do you identify the quadrant of a point (x, y)?

Back

To identify the quadrant, check the signs of x and y: Quadrant I (both positive), Quadrant II (x negative, y positive), Quadrant III (both negative), Quadrant IV (x positive, y negative).

Front

What is the x-axis?

Back

The x-axis is the horizontal line on a coordinate plane where the y-coordinate is zero.

Front

What is the y-axis?

Back

The y-axis is the vertical line on a coordinate plane where the x-coordinate is zero.

Front

What is the origin in a coordinate plane?

Back

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

Front

How do you plot a point on a coordinate plane?

Back

To plot a point, start at the origin, move along the x-axis to the x-coordinate, and then move vertically to the y-coordinate.
