Plotting Points

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to represent a point in a coordinate system, 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 of a point 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 of a point 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 (positive x-direction), and then move 2 units up (positive y-direction).

Front

What is the coordinate of the origin in a coordinate plane?

Back

The coordinate of the origin is (0, 0).

Front

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

Back

It is located in the second quadrant of the coordinate plane.

Front

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

Back

It is located in the fourth quadrant of the coordinate plane.

Front

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

Back

The distance is 4 units, calculated as |3 - (-1)|.

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 labeled 'A' on a graph?

Back

Locate point 'A' on the graph and read the x-coordinate and y-coordinate to write it as (x, y).
