Integers & Coordinate Plane Test Review

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). Each point on the plane is defined by an ordered pair (x, y).

Front

How do you find 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 -5 is 5, written as |-5| = 5.

Front

What does the point (x, y) represent in the coordinate plane?

Back

In the coordinate plane, (x, y) represents a specific location where 'x' is the horizontal distance from the origin and 'y' is the vertical distance from the origin.

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. For example, -100, -52, -13, 4, 72.

Front

What is the opposite of a number?

Back

The opposite of a number is the number that is the same distance from zero but in the opposite direction. For example, the opposite of -200 is 200.

Front

How do you identify the largest integer among negative numbers?

Back

To identify the largest integer among negative numbers, choose the one closest to zero. For example, between -1.5, -0.8, and -0.3, the largest is -0.3.

Front

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

Back

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

Front

What is a quadrant in the coordinate plane?

Back

A quadrant is one of the four sections of the coordinate plane, created by the x-axis and y-axis. Quadrants are numbered I, II, III, and IV, starting from the upper right and moving counterclockwise.

Front

How do you plot a point on the coordinate plane?

Back

To plot a point (x, y), start at the origin (0, 0), move 'x' units along the x-axis, and then 'y' units up or down along the y-axis.
