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). Each point on the plane is defined by an ordered pair of numbers (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, and it is the point where the x-axis and y-axis intersect.

Front

How do you identify the quadrant of a point with positive x and positive y coordinates?

Back

A point with positive x and positive y coordinates is located in Quadrant I.

Front

What is the x-coordinate in the ordered pair (3, -4)?

Back

The x-coordinate is 3.

Front

What is the y-coordinate in the ordered pair (-2, 5)?

Back

The y-coordinate is 5.

Front

Which quadrant contains the point (-3, 2)?

Back

Quadrant II.

Front

What is the significance of the x-axis and y-axis in a coordinate plane?

Back

The x-axis is the horizontal line, and the y-axis is the vertical line that define the coordinate plane and help locate points.

Front

How do you plot the point (4, -6) on a coordinate plane?

Back

Start at the origin (0, 0), move 4 units to the right (positive x-direction), and then move 6 units down (negative y-direction).

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.
