Plotting points

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 (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 (1, -3) on a coordinate plane?

Back

Start at the origin (0, 0), move 1 unit to the right (positive x-direction), and then move 3 units down (negative y-direction).

Front

What is the coordinate for point C if it is located at (-3, 5)?

Back

The coordinate for point C is (-3, 5).

Front

How do you identify the point (1, 3) on a graph?

Back

Move 1 unit to the right and 3 units up from the origin.

Front

What is the correct format for writing coordinates?

Back

Coordinates should be written in the format (x, y) with a comma separating the two values.

Front

Where is point G located if its coordinates are (3, -5)?

Back

Point G is located 3 units to the right and 5 units down from the origin.

Front

What are the coordinates for point B if it is at (0, 4)?

Back

The coordinates for point B are (0, 4), meaning it is on the y-axis, 4 units up from the origin.

Front

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

Back

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