Algebra 2 Equations

Solve the system by graphing.
2x + 4y = 12
x + y = 5

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

Solve the system by graphing.
y = -x + 3
2y - 3x = -4

• (1, 2)
• (-1, -2)
• (2, 1)
• (-2, -1)

Without graphing, classify each system as independent, dependent, or inconsistent.
-3x + y = 4
3x - y = 1

• Independent
• Dependent
• Inconsistent

Without graphing, classify each system as independent, dependent, or inconsistent.
x - 3y = 2
4x - 12y = 8

• Independent
• Dependent
• Inconsistent

Solve the system by substitution.
x + 12y = 68
x = 8y - 12
