Coordinate Plane and Integers Review

Front

What is a coordinate plane?

Back

A 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 of numbers (x, y).

Front

What are integers?

Back

Integers are whole numbers that can be positive, negative, or zero. Examples include -3, 0, and 5.

Front

How do you find the distance between two points on a coordinate plane?

Back

The distance between two points (x1, y1) and (x2, y2) can be found using the formula: Distance = |x2 - x1| + |y2 - y1|.

Front

What does the absolute value of a number represent?

Back

The absolute value of a number represents its distance from zero on the number line, regardless of direction. For example, |5| = 5 and |-5| = 5.

If you have 5 apples and eat 2, how many do you have left?

Back

3 apples.

Front

What is the x-coordinate of a point?

Back

The x-coordinate of a point is the first number in an ordered pair (x, y) that indicates its horizontal position on the coordinate plane.

Front

What is the y-coordinate of a point?

Back

The y-coordinate of a point is the second number in an ordered pair (x, y) that indicates its vertical position on the coordinate plane.

Front

How do you represent a point in the coordinate plane?

Back

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

Front

What is the distance between the points (7, -2) and (11, -2)?

Back

4 units.

Front

What expression represents the distance between Point A (-5, 3) and Point B (2, 3)?

Back

The expression is | -5 | + | 2 |.
