Coordinate Planes

Front

What is an ordered pair?

Back

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

Front

What does the first number in an ordered pair represent?

Back

The first number in an ordered pair represents the x-coordinate, which indicates the horizontal position on the coordinate plane.

Front

What does the second number in an ordered pair represent?

Back

The second number in an ordered pair represents the y-coordinate, which indicates the vertical position on the coordinate plane.

Front

How do you plot the point (3, 5) on a coordinate plane?

Back

Start at the origin (0,0), move 3 units to the right (x-coordinate), and then move 5 units up (y-coordinate).

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

What are the four quadrants of a coordinate plane?

Back

The four quadrants are: Quadrant I (positive x and y), Quadrant II (negative x and positive y), Quadrant III (negative x and y), Quadrant IV (positive x and negative y).

Front

What is the origin in a coordinate plane?

Back

The origin is the point where the x-axis and y-axis intersect, represented by the ordered pair (0,0).

Front

If you move 2 units left and 3 units down from the point (4, 5), where do you end up?

Back

You end up at the point (2, 2).

Front

What is the x-axis?

Back

The x-axis is the horizontal line on a coordinate plane where the y-coordinate is 0.

Front

What is the y-axis?

Back

The y-axis is the vertical line on a coordinate plane where the x-coordinate is 0.
