Coordinate Planes RAM Time

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).

Front

What does the x-axis represent?

Back

The x-axis represents the horizontal line in a coordinate plane, where the y-coordinate is zero.

Front

What does the y-axis represent?

Back

The y-axis represents the vertical line in a coordinate plane, where the x-coordinate is zero.

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 is the first number in an ordered pair called?

Back

The first number in an ordered pair is called the x-coordinate.

Front

What is the second number in an ordered pair called?

Back

The second number in an ordered pair is called the y-coordinate.

Front

What are the four quadrants of a coordinate plane?

Back

The four quadrants are: Quadrant I (x > 0, y > 0), Quadrant II (x < 0, y > 0), Quadrant III (x < 0, y < 0), Quadrant IV (x > 0, y < 0).

Front

What does reflection over the x-axis mean?

Back

Reflection over the x-axis means that a point (x, y) is transformed to (x, -y).

Front

What does reflection over the y-axis mean?

Back

Reflection over the y-axis means that a point (x, y) is transformed to (-x, y).

Front

How do you identify the quadrant of a point?

Back

To identify the quadrant of a point, look at the signs of the x and y coordinates.
