Coordinate Plane

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). It is used to locate points using ordered pairs (x, y).

Front

What are the axes in a coordinate plane?

Back

The x-axis is the horizontal line, and the y-axis is the vertical line. They intersect at the origin (0, 0).

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to locate a point on the coordinate plane, written in the form (x, y).

Front

How do you graph the point (7, 1) on the coordinate plane?

Back

Start at the origin (0, 0). Move 7 units to the right along the x-axis and 1 unit up along the y-axis.

Front

What does the point (0, 0) represent on the coordinate plane?

Back

The point (0, 0) is called the origin, where the x-axis and y-axis intersect.

Front

If you move 4 units left and 2 units down from the point (5, 5), what is the new ordered pair?

Back

The new ordered pair is (1, 3).

Front

What is the first quadrant in the coordinate plane?

Back

The first quadrant is the area where both x and y coordinates are positive, located in the top right section of the coordinate plane.

Front

How do you find the x-coordinate of a point?

Back

The x-coordinate is the first number in an ordered pair (x, y) and indicates the horizontal position on the coordinate plane.

Front

How do you find the y-coordinate of a point?

Back

The y-coordinate is the second number in an ordered pair (x, y) and indicates the vertical position on the coordinate plane.

Front

What is the distance from the origin to the point (3, 4)?

Back

The distance is 5 units, calculated using the Pythagorean theorem: √(3² + 4²) = √(9 + 16) = √25 = 5.
