Integers and the coordinate plane

Front

What is an integer?

Back

An integer is a whole number that can be positive, negative, or zero. Examples include -3, 0, and 5.

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

How do you identify the coordinates of a point on the coordinate plane?

Back

Coordinates are written as (x, y), where 'x' is the horizontal position and 'y' is the vertical position.

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, |-7| = 7.

Front

How do you find the perimeter of a rectangle?

Back

The perimeter of a rectangle is found by adding the lengths of all four sides or using the formula P = 2(length + width).

Front

What is the area of a rectangle?

Back

The area of a rectangle is calculated by multiplying its length by its width. A = length × width.

Front

How do you order integers from least to greatest?

Back

To order integers from least to greatest, list them starting from the smallest value to the largest value. For example, -2, -1, 0, 4.

Front

What does it mean for a number to be less than zero?

Back

A number is less than zero if it is negative. For example, -7 is less than zero.

Front

How do you determine which two integers a decimal lies between?

Back

To find which two integers a decimal lies between, round the decimal to the nearest whole number and identify the integers on either side.

Front

What is the difference between positive and negative integers?

Back

Positive integers are greater than zero (e.g., 1, 2, 3), while negative integers are less than zero (e.g., -1, -2, -3).
