Chapter 6 Review Integers and the Coordinate Plane

Front

What is an integer?

Back

An integer is a whole number that can be positive, negative, or zero, but not a fraction or decimal.

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, |-5| = 5.

Front

How do you add integers with different signs?

Back

To add integers with different signs, subtract the smaller absolute value from the larger absolute value and keep the sign of the integer with the larger absolute value.

Front

What is the result of -32 + 2?

Back

-30

Front

How do you subtract integers?

Back

To subtract integers, add the opposite of the integer you are subtracting. For example, 8 - 18 is the same as 8 + (-18).

Front

What is the result of 8 - 18?

Back

-10

Front

How do you order integers from least to greatest?

Back

To order integers from least to greatest, compare their values and arrange them starting from the smallest to the largest.

Front

Order the following integers from least to greatest: 5, -20, -10, 10, 15.

Back

-20, -10, 5, 10, 15

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 is defined by an ordered pair (x, y).

Front

How do you plot a point in the coordinate plane?

Back

To plot a point, start at the origin (0,0), move along the x-axis to the x-coordinate, and then move vertically to the y-coordinate.
