Plotting Points on a Graph

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to locate a point on a graph, written in the form (x, y).

Front

What are the coordinates for the origin in the coordinate plane?

Back

(0, 0) is the coordinate for the origin.

Front

How do you identify the x-coordinate in an ordered pair?

Back

The x-coordinate is the first number in an ordered pair (x, y) and represents the horizontal position.

Front

How do you identify the y-coordinate in an ordered pair?

Back

The y-coordinate is the second number in an ordered pair (x, y) and represents the vertical position.

Front

What does the point (3, 2) represent on a graph?

Back

The point (3, 2) represents a location 3 units to the right and 2 units up from the origin.

Front

What is the significance of negative coordinates in a graph?

Back

Negative coordinates indicate positions to the left (for x) or below (for y) the origin.

Front

What is the coordinate for Point B if it is located 4 units left and 2 units up from the origin?

Back

The coordinate for Point B is (-4, 2).

Front

If a point has coordinates (-2, -3), where is it located?

Back

The point (-2, -3) is located 2 units left and 3 units down from the origin.

Front

What is the relationship between the x-axis and y-axis?

Back

The x-axis is the horizontal line, while the y-axis is the vertical line; they intersect at the origin (0, 0).

Front

How do you plot the point (1, -5) on a graph?

Back

Move 1 unit to the right on the x-axis and 5 units down on the y-axis.
