Integers, Rational Numbers and Coordinate Plane

Front

What are integers?

Back

Integers are whole numbers that can be positive, negative, or zero. Examples include -3, 0, and 5.

Front

What are rational numbers?

Back

Rational numbers are numbers that can be expressed as a fraction of two integers, where the denominator is not zero. Examples include 1/2, -3, and 0.75.

Front

What is the coordinate plane?

Back

The 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 (x, y).

Front

What are the coordinates of the origin in the coordinate plane?

Back

The coordinates of the origin are (0, 0).

Front

How do you represent a point in the coordinate plane?

Back

A point in the coordinate plane is represented by an ordered pair (x, y), where 'x' is the horizontal position and 'y' is the vertical position.

Front

What does the absolute value of a number represent?

Back

The absolute value of a number represents its distance from zero on the number line, regardless of direction. For example, | -3 | = 3 and | 3 | = 3.

Front

How do you compare rational numbers?

Back

To compare rational numbers, convert them to a common denominator or decimal form, then determine which is greater or lesser.

Front

What is the result of | -1.8 | > 1.6?

Back

True, because | -1.8 | equals 1.8, which is greater than 1.6.

Front

Order the following rational numbers from greatest to least: -0.45, -1/3, 4/5, 0.25, -1/2.

Back

4/5, 0.25, -1/3, -0.45, -1/2.

What integer represents a temperature of 8 degrees below zero?

Back

-8.
