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 is an ordered pair?

Back

An ordered pair is a pair of numbers used to locate a point on a coordinate plane, written in the form (x, y).

Front

What does it mean for a number to be its own opposite?

Back

A number is its own opposite if it is equal to its negative. The only number that is its own opposite is 0.

Front

What is absolute value?

Back

The absolute value of a number is its distance from 0 on the number line, regardless of direction. It is always a non-negative number.

Front

What is the absolute value of -8/5?

Back

The absolute value of -8/5 is 8/5.

Front

How do you identify a point in Quadrant IV?

Back

A point is in Quadrant IV if its x-coordinate is positive and its y-coordinate is negative.

Front

What are the coordinates of Point A if it is located at (-4, 1)?

Back

The coordinates of Point A are (-4, 1).

Front

How do you plot a point on a coordinate plane?

Back

To plot a point, start at the origin (0, 0), move along the x-axis to the x-coordinate, and then move vertically to the y-coordinate.

Front

What is the significance of the x-axis and y-axis?

Back

The x-axis is the horizontal line on a coordinate plane, while the y-axis is the vertical line. They are used to define the position of points.
