Graphing Points on the Coordinate Plane

Front

What is the definition of 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 (x-coordinate) represents the horizontal position on the coordinate plane.

Front

What does the second number in an ordered pair represent?

Back

The second number (y-coordinate) represents the vertical position on the coordinate plane.

Front

How do you plot the point (3, 2) on a coordinate plane?

Back

Start at the origin (0, 0), move 3 units to the right (x-axis), then move 2 units up (y-axis).

Front

What is the location of the point (0, 0)?

Back

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

Front

If a point has a negative x-coordinate and a positive y-coordinate, in which quadrant is it located?

Back

It is located in Quadrant II.

Front

If a point has a positive x-coordinate and a negative y-coordinate, in which quadrant is it located?

Back

It is located in Quadrant IV.

Front

What is the distance between the points (2, 3) and (2, -1)?

Back

The distance is 4 units, calculated by finding the difference in the y-coordinates: 3 - (-1) = 4.

Front

What is the significance of the x-axis and y-axis in a coordinate plane?

Back

The x-axis is the horizontal line, and the y-axis is the vertical line that intersect at the origin, dividing the plane into four quadrants.

Front

How do you identify the coordinates of a point on a graph?

Back

Locate the point's position by counting units along the x-axis (horizontal) and y-axis (vertical) from the origin.
