## Chapter 6, Lesson 3

**6-3.A** plot ordered pairs on a coordinate plane

**Which of the following statements are true?I** If a point is on the x-axis, its x-coordinate is 0.

**II**If a point is in Quadrant IV, both coordinates are negative.

**III**If a point is in Quadrant II, the value of its y-coordinate is always greater than the value of its x-coordinate.
