Lesson 1: Graph on the Coordinate Plane6.NOS.6

I can…

I can plot and identify points on the coordinate plane using ordered pairs.

Key words

• Coordinate plane — A grid with a line going across and a line going up to plot points.
• Ordered pair — Two numbers (x, y) that tell where a point is on a grid.
• Origin — The point (0, 0) where the two grid lines cross.
• Quadrant — One of the four parts of a coordinate grid, numbered I to IV.
• Reflection — A flipped, mirror image across a line.
• Integer — Whole numbers and their opposites, like -2, -1, 0, 1, 2.

Steps

1. I will plot the point (5, 4). The 5 is the x-coordinate, and the 4 is the y-coordinate.
2. I start at the origin, which is (0, 0).
3. First I move 5 units to the right along the x-axis.
4. Then I move 4 units up. I place my dot. That is the point (5, 4).

Try it

Point P is located 6 units right and 3 units up from the origin. What ordered pair names point P?

Check your answer

(6, 3)

Right 6 = x-coordinate of 6, Up 3 = y-coordinate of 3. The ordered pair is (6, 3).
