What is the first coordinate in an ordered pair, and what direction does it tell you to move from the origin?

The x-coordinate, and it tells you how far to move horizontally (left or right) from the origin.

Describe the steps you would take to plot the point (-2, 5) on a coordinate plane.

Start at the origin, move 2 units to the left along the x-axis, and then move 5 units up parallel to the y-axis. Plot the point there.

Explain why the order of coordinates matters when plotting points.

Switching the order of the x and y coordinates changes the location of the point on the coordinate plane. For example, (2, 3) is a different point than (3, 2).

Key concepts students will learn:

•
The x-axis is horizontal, while the y-axis is vertical on a coordinate plane.
•
When plotting points, the x coordinate always comes first, and the y coordinate comes second in the ordered pair.
•
To plot the point (4, 7), start at the origin, move right 4 units on the x-axis, and then move up 7 units on the y-axis.
