Positive and Negative Numbers and the Coordinate Plane

Front

What is a positive number?

Back

A positive number is a number greater than zero, representing a quantity or value that is above zero.

Front

What is a negative number?

Back

A negative number is a number less than zero, representing a quantity or value that is below zero.

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 represent a point on the coordinate plane?

Back

A point is represented by an ordered pair (x, y), where 'x' is the horizontal position and 'y' is the vertical position.

Front

What does the x-axis represent?

Back

The x-axis represents the horizontal line in the coordinate plane, where values increase from left to right.

Front

What does the y-axis represent?

Back

The y-axis represents the vertical line in the coordinate plane, where values increase from bottom to top.

Front

How do you find the distance between two points on the same horizontal line?

Back

To find the distance, subtract the x-coordinates of the two points.

Front

What is the result of adding a positive number and a negative number?

Back

The result depends on the absolute values; if the positive number is greater, the result is positive, and if the negative number is greater, the result is negative.

Front

What is the result of subtracting a negative number from a positive number?

Back

Subtracting a negative number is the same as adding its positive counterpart.

Front

How do you represent a withdrawal from a bank account?

Back

A withdrawal is represented by a negative number, indicating a decrease in the account balance.
