## Spectrum Math Grade 5 Chapter 10 Lesson 10.1 The Coordinate System Answers Key

A point on a grid is located by using an ordered pair. An ordered pair lists the x-axis point first and then the y-axis point.

Points located on the same grid are called coordinate points, or coordinates.

(10, 3)

(x, y)

1. Count right ten lines.

2. From that point, go up 3.

3. Draw a point.

**Identify the ordered pair from each grid.**

Question 1.
