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.

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 -4 is 4.

Front

What does it mean to order integers from least to greatest?

Back

Ordering integers from least to greatest means arranging them in ascending order, starting with the smallest number and ending with the largest.

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 plot a point on the coordinate plane?

Back

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

Front

What is the ordered pair for the point located 3 units east and 2 units north of the origin?

Back

The ordered pair is (3, 2).

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). Zero is neither positive nor negative.

Front

How do you add two 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 perimeter of a rectangle with length 10 units and width 4 units?

Back

The perimeter is calculated as P = 2(length + width). So, P = 2(10 + 4) = 28 units.

Front

What is the result of -5 + 3?

Back

The result is -2.
