3. Solve the system by graphing.
Graphing Systems of Equations
LESSON 3-1
Additional Examples
Solve the system by graphing.
x + 3y = 2
3x + 3y = –6

4. Classify the system without graphing.
Graphing Systems of Equations
LESSON 3-1
Additional Examples
Classify the system without graphing.
y = 3x + 2
–6x + 2y = 4

5. Practice
1. solve by graphing
y = x – 2
y = -2x + 7

6. 2. 2x + 4y = 12
x + y = 2

7. 3. 3 = 4y + x
4y = -x + 3

8. Practice answers 1. ( 3, 1 ) 2. ( -2, 4 ) 3. infinitely many solutions
