Unit 5 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 (QI): (+, +), Quadrant II (QII): (-, +), Quadrant III (QIII): (-, -), Quadrant IV (QIV): (+, -).

Front

In which quadrant would you find the point (-23, -4)?

Back

Quadrant III (QIII).

Front

What is an ordered pair?

Back

A pair of numbers (x, y) that represent a point on the coordinate plane, where 'x' is the horizontal position and 'y' is the vertical position.

Front

What is the X coordinate in the ordered pair (5, -8)?

Back

5.

Front

What is the Y coordinate in the ordered pair (5, -8)?

Back

-8.

Front

How do you find the distance between two points on the same vertical line, like (34, -19) and (34, 18)?

Back

Subtract the Y coordinates: |18 - (-19)| = 37 units.

Front

What is the length of the longest side of a rectangle with coordinates (3, 2), (-2, 2), (-2, -1), (3, -1)?

Back

5 units.

Front

What does the term 'axis' refer to in the coordinate plane?

Back

A reference line used to measure distances; the x-axis is horizontal, and the y-axis is vertical.

Front

What is the origin in the coordinate plane?

Back

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