Rewrite the equation in slope-intercept form. (y = mx + b Lesson 4.2)

4x + y = 0


2x – 2y = 20


-5x – 10y = 40

Find three ordered pairs that are solutions of the equation. Then graph the equation.

(Lesson 4.2)y = 3x – 4


(Lesson 4.2)y = 2x + 3


(Lesson 4.2)y = -5x + 5


(Lesson 4.2)5x + y = 5

Find the x-intercept and the y-intercept of the line. Graph the equation. (Lesson 4.4)

y = 2x + 6


x – y = 4


y – 3x = -15


3x – y = 6

Find the slope of the line passing through the points. (Lesson 4.5)

(0, 0), (6, 2)


(1, -2), (-4, -4)


(2, 2), (-4, -2)

The variables x and y vary directly. Write an equation that relates x and y. (Lesson 4.6)

x = 4, y = 16


• x = 8, y = 40


x = 12, y = 60

Write the equation in slope-intercept form (y = mx + b). Identify the slope and the y-intercept. (Lesson 4.7)

y – 2 = 2xm = b=


x = -y + 3m= b=


4x + y = 4m= b=

Graph the equation. (Lesson 4.7)

2x + 2y = 4


-8x – 2y = 16


-2x + y = 0
