## Chapter 6, Lesson 7

**6-7.A** identify the slope and *y*-intercept of a line from an equation

**Which of these lines have a slope of 3 and a y-intercept of 2?I** 2

*y*= 3

*x*+ 2

**II**

*y*= 3

*x*— 2

**III**

*y*— 2 = 3

*x*

**(a)**I and II only

**(b)**I and III only

**(c)**I only

**(d)**III only

**6-7.B** graph an equation in slope-intercept form

**Graph the line whose equation is ****.**

**6-7.C** write an equation of a line using slope and y-intercept **Write, in standard form, the equation of the line whose slope = ****and whose y-intercept = 3.**
