Front

What is an ordered pair in the coordinate plane?

Back

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

Front

How do you determine the location of a point R on the coordinate plane?

Back

You identify the x-coordinate and y-coordinate of point R, which together form an ordered pair (x, y).

Front

What does a negative integer represent in a real-world context?

Back

A negative integer can represent a value below zero, such as depth below sea level or a loss in score.

Front

What is the absolute value of a number?

Back

The absolute value of a number is its distance from zero on the number line, regardless of direction. For example, |-8| = 8.

Front

How do you find the opposite of a number?

Back

The opposite of a number is found by changing its sign. For example, the opposite of 4 is -4.

Front

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

Back

The y-axis is the vertical line in a coordinate plane where the x-coordinate is zero.

Front

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

Back

The x-axis is the horizontal line in a coordinate plane where the y-coordinate is zero.

Front

How do you calculate the change in a test score?

Back

To calculate the change in a test score, subtract the old score from the new score.

Front

What does it mean if a student has the greatest change in their test score?

Back

It means that the difference between their highest and lowest scores is larger than that of other students.

Front

What is the representation of depth in integers?

Back

Depth is represented by negative integers. For example, a depth of 25 feet below the surface is represented as -25.
