Coordinate Plane Review

Front

What is the coordinate plane?

Back

The coordinate plane is 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 is an ordered pair?

Back

An ordered pair is a pair of numbers used to represent a point on the coordinate plane, written in the form (x, y), where x is the horizontal position and y is the vertical position.

Front

What are the four quadrants of the 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

How do you identify the coordinates of a point on the coordinate plane?

Back

To identify the coordinates of a point, locate the point's position relative to the x-axis (horizontal) and y-axis (vertical) and express it as an ordered pair (x, y).

Front

What is the significance of the origin in the coordinate plane?

Back

The origin is the point where the x-axis and y-axis intersect, represented by the ordered pair (0, 0). It serves as the reference point for all other points on the plane.

Front

How do you plot a point given its coordinates?

Back

To plot a point, start at the origin, move horizontally to the x-coordinate, and then vertically to the y-coordinate, marking the point where these two movements intersect.

Front

What is the x-axis?

Back

The x-axis is the horizontal line in the coordinate plane where the y-coordinate is zero, used to measure the horizontal position of points.

Front

What is the y-axis?

Back

The y-axis is the vertical line in the coordinate plane where the x-coordinate is zero, used to measure the vertical position of points.

Front

What are negative coordinates and where are they located?

Back

Negative coordinates are values less than zero, located in Quadrants II and III for x-coordinates and Quadrants III and IV for y-coordinates.

Front

How do you determine which quadrant a point is in?

Back

To determine the quadrant of a point, examine the signs of the x and y coordinates: both positive (Quadrant I), x negative and y positive (Quadrant II), both negative (Quadrant III), x positive and y negative (Quadrant IV).
