Coordinate Plane Pairs

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).

Front

What are the four quadrants of the coordinate plane?

Back

Quadrant 1 (x > 0, y > 0), Quadrant 2 (x < 0, y > 0), Quadrant 3 (x < 0, y < 0), Quadrant 4 (x > 0, y < 0).

Front

What does an ordered pair represent?

Back

A pair of numbers (x, y) that define a point's location on the coordinate plane.

Front

What is the x-coordinate in an ordered pair?

Back

The first number in an ordered pair, representing the horizontal position on the coordinate plane.

Front

What is the y-coordinate in an ordered pair?

Back

The second number in an ordered pair, representing the vertical position on the coordinate plane.

Front

What is the origin in the coordinate plane?

Back

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

Front

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

Back

Determine the signs of x and y: both positive in Quadrant 1, x negative and y positive in Quadrant 2, both negative in Quadrant 3, and x positive and y negative in Quadrant 4.

Front

What is the significance of the point (0, y)?

Back

It lies on the y-axis, where x is always 0.

Front

What is the significance of the point (x, 0)?

Back

It lies on the x-axis, where y is always 0.

Front

If a point is in Quadrant 1, what can you say about its coordinates?

Back

Both the x-coordinate and y-coordinate are positive.
