Coordinate Plane - 4 Quadrants

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 ordered pair (x, y) represent?

Back

The ordered pair (x, y) represents a point on the coordinate plane, where 'x' is the horizontal position and 'y' is the vertical position.

Front

How do you plot the point (2, 3) on the coordinate plane?

Back

Start at the origin (0, 0), move 2 units to the right (positive x direction), and then move 3 units up (positive y direction).

Front

What is the x-coordinate in the ordered pair (4, -5)?

Back

The x-coordinate is 4.

Front

What is the y-coordinate in the ordered pair (-3, 7)?

Back

The y-coordinate is 7.

Front

If a point is in Quadrant II, what can you say about its coordinates?

Back

In Quadrant II, the x-coordinate is negative and the y-coordinate is positive.

Front

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

Back

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

Front

How do you identify which quadrant a point is in?

Back

Look at the signs of the x and y coordinates: Quadrant I (both positive), Quadrant II (x negative, y positive), Quadrant III (both negative), Quadrant IV (x positive, y negative).

Front

What does it mean if a point has a negative x-coordinate and a positive y-coordinate?

Back

It means the point is located in Quadrant II of the coordinate plane.
