Graphing on the Coordinate Plane

Front

What is the coordinate plane?

Back

A two-dimensional surface formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis), used to locate points using ordered pairs.

Front

What are the four quadrants of the coordinate plane?

Back

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 ordered pair (x, y) represent?

Back

The x-coordinate represents the horizontal position, and the y-coordinate represents the vertical position of a point on the coordinate plane.

Front

How do you identify the quadrant of a point?

Back

By examining the signs of the x and y coordinates: both positive in Quadrant I, x negative and y positive in Quadrant II, both negative in Quadrant III, and x positive and y negative in Quadrant IV.

Front

What are the coordinates of the origin?

Back

(0, 0), where the x-axis and y-axis intersect.

Front

What is the x-axis?

Back

The horizontal line on the coordinate plane where y = 0.

Front

What is the y-axis?

Back

The vertical line on the coordinate plane where x = 0.

Front

How do you plot a point on the coordinate plane?

Back

Start at the origin (0, 0), move horizontally to the x-coordinate, then move vertically to the y-coordinate.

Front

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

Back

The distance is 4 units, calculated as |3 - (-1)|.

Front

What is the distance between the points (4, -3) and (0, -3)?

Back

The distance is 4 units, calculated as |4 - 0|.
