Review - Rational Numbers, Inequalities, and Coordinate Plane

Front

What is a rational number?

Back

A rational number is any number that can be expressed as the quotient or fraction of two integers, where the denominator is not zero.

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, the absolute value of -4 is 4.

What does it mean for a number to be positive?

Back

A positive number is any number greater than zero.

Front

What does it mean for a number to be negative?

Back

A negative number is any number less than zero.

Front

What is zero on a number line?

Back

Zero is the point on a number line that separates positive numbers from negative numbers.

Front

How do you represent the point (0, 2) on a coordinate plane?

Back

The point (0, 2) is located at the intersection of the y-axis and the line y = 2.

Front

What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions, showing that one is greater than, less than, or not equal to the other.

Front

How do you order numbers from least to greatest?

Back

To order numbers from least to greatest, arrange them starting from the smallest value to the largest value.

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).

Front

What is the significance of the point (0, 0) on a coordinate plane?

Back

The point (0, 0) is known as the origin, where the x-axis and y-axis intersect.
