Coordinate Crash Course
This is the special name for the point (0, 0) where the x-axis and y-axis meet.
What is the origin?
To plot the point (4, 0), you move 4 units to the right from the origin and this many units up or down.
What is 0?
If a treasure map uses a coordinate plane, the x-coordinate usually tells you how far east or west to go, and the y-coordinate usually tells you this direction.
What is north or south?
A pair of numbers, written like (x, y), that tells you the exact location of a point on a coordinate plane.
What is an ordered pair?
This ordered pair represents the location of the point shown.
What is (2, 5)?
On a city map where the origin is downtown, if a bookstore is located at (6, 4), the 6 means it is 6 blocks east, and the 4 means it is 4 blocks in this direction.
What is north?
This is the horizontal number line on a coordinate plane, often labeled with the letter x
What is the x-axis?
To plot the point (3, 1), you first move 3 units right along the x-axis, then this direction for 1 unit along the y-axis.
What is up?
A robot starts at the origin (0, 0). It moves 4 units right, then 3 units up. This is its final ordered pair location.
What is (4,3)?
In the ordered pair (7, 2), this specific number tells you how far to travel from the origin in the direction of the y-axis.
What is 2? / What is the y-coordinate?
A point on the coordinate plane that has an x-coordinate of 5 and a y-coordinate that is 3 less than its x-coordinate.
What is (5,2)
A city planner uses a coordinate grid. A park is located at (5, 8) and a library is at (5, 2). This is the distance between the park and the library in grid units.
What is 6 units?
