## Chapter 6, Lesson 5

**6-5.A** read and plot ordered pairs on a coordinate plane

**Which of these ordered pairs are on the y-axis?I** (0, 0)

**II**(0, —8)

**III**(—8, 0)

**(a)**I only

**(b)**I and II only

**(c)**I and III only

**(d)**II only

**6-5.B** solve two-step equations

**Solve each equation.**

**a.** 0 = —40*x* + 320 **b.** 600 = 15*w* + 600
