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 distance between two points on a coordinate plane?

Back

To find the distance between two points (x1, y1) and (x2, y2), use the formula: Distance = |y2 - y1| if x1 = x2 (vertical distance) or Distance = |x2 - x1| if y1 = y2 (horizontal distance).

What is the absolute value of a number?

Back

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

Front

What is the distance between the points (-2, -4) and (-2, -12)?

Back

The distance is 8.

Front

What is the distance between the points (-3, 5) and (8, 5)?

Back

The distance is 11.

Front

How do you calculate the distance between two points with the same y-coordinate?

Back

If two points have the same y-coordinate, the distance is the absolute difference of their x-coordinates. For example, for points (x1, y) and (x2, y), Distance = |x2 - x1|.

Front

What does it mean for a number to be negative?

Back

A negative number is less than zero and is represented to the left of zero on the number line. Examples include -1, -2, and -10.
