Graphing on the Coordinate Plane Flashcard

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 x-value represent in an ordered pair?

Back

The x-value represents the horizontal position of a point on the coordinate plane.

Front

What does the y-value represent in an ordered pair?

Back

The y-value represents the vertical position of a point on the coordinate plane.

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

What is the x-axis?

Back

The x-axis is the horizontal number line on a coordinate plane.

Front

What is the y-axis?

Back

The y-axis is the vertical number line on a coordinate plane.

Front

How do you identify the quadrant of a point?

Back

The quadrant of a point is determined by the signs of its x and y values: Quadrant I (+,+), Quadrant II (-,+), Quadrant III (-,-), Quadrant IV (+,-).

Front

What is the point (-4, 5) in terms of its x and y values?

Back

In the point (-4, 5), -4 is the x-value and 5 is the y-value.

Front

What is the significance of the point (0, y)?

Back

The point (0, y) lies on the y-axis, where x is always 0.

Front

What is the significance of the point (x, 0)?

Back

The point (x, 0) lies on the x-axis, where y is always 0.
