Solve for x and y
2x − 3y = −1
 y = x − 1

• (-2,-3)
• (0,-1)
• (3,4)
• (4,3)

Solve the system by Substitution. 
y=2x
x + y = 9

• (6, 3)
• (3, 6)
• (-3, -6)
• no solution

Solve by graphing. (use the graphs I sent home with you)

y = 2x + 1

y = 4x - 1

• (1,3)

• (-1,-3)

• (-1,3)

• (3,1)

y = -2x + 18
y = 8

• (5, 8)
• (-5, 8)
• (2, 8)
• (-2, 8)
