Solve by Graphing
Using Desmos, solve each system by graphing.
y = x - 2
x + y = 10
(6, 4)
Using Desmos, classify each system as independent, dependent, or inconsistent.
3x + 2y = 7
3x - 15 = -6y
Independent
(intersecting lines = one solution)
Solve each system by substitution.
x = y - 2
3x - y = 6
(4, 6)
Solve the system by elimination.
-x + 3y = -1
x - 2y = 2
(4, 1)
Use any method to solve the system.
2x + y = 0
4x + 2y = -11
No Solution
Using Desmos, solve each system by graphing.
4x + 3y = -16
-x + y = 4
(-4, 0)
Using Desmos, classify each system as independent, dependent, or inconsistent.
x + y = 6
3x + 3y = 3
Inconsistent
(parallel lines = no solution)
Solve each system by substitution.
6x - 3y = -33
2x + y = -1
(-3, 5)
Solve the system by elimination.
-x + y = 3
5x + y = 9
(1, 4)
Use any method to solve the system.
x + 5y = 1
2x + 10y = 2
Infinitely Many Solutions
Using Desmos, solve each system by graphing.
x + y = 6
x - y = 4
(5, 1)
Using Desmos, classify each system as independent, dependent, or inconsistent.
x + 3y = 9
-2x - 6y = -18
Dependent
(same line = infinitely many solutions)
Solve each system by substitution.
4x = 8y
2x + 5y = 27
(6, 3)
Solve the system by elimination.
x + 2y = 10
3x - y = 9
(4, 3)
Use any method to solve the system.
3x - 2y = 5
-6x + 4y = 7
No Solution
