Integers and Coordinate Plane Test

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 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 it mean to reflect a point over the x-axis?

Back

To reflect a point over the x-axis, you change the sign of the y-coordinate while keeping the x-coordinate the same.

Front

What does it mean to reflect a point over the y-axis?

Back

To reflect a point over the y-axis, you change the sign of the x-coordinate while keeping the y-coordinate the same.

Front

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

Back

The result depends on the absolute values; if the positive integer is larger, the result is positive, and if the negative integer is larger, the result is negative.

Front

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

Back

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

Front

How do you compare two integers?

Back

You can compare integers using the symbols > (greater than), < (less than), or = (equal to).

Front

What is the absolute value of an integer?

Back

The absolute value of an integer is its distance from zero on the number line, regardless of direction.

Front

What is the sum of -5 and 3?

Back

The sum of -5 and 3 is -2.
