1.	Which is the correct graph for the system of equations x + y = 4 and y = x – 2?
		A.		B.
		C.		D.
		Hint
	2.	Solve the system of equations x – y = 3 and 2y = 2x – 6.
		A.	The graphs appear to be parallel lines, so there is no solution to the system.
		B.	(-3,0)
		C.	(0,-3)
		D.	Each equation has the same graph, so there are infinitely many solutions.
		Hint
	3.	Solve the system of equations and 2y – 4x = 12.
		A.	The graphs appear to be parallel lines, so there is no solution to the system.
		B.	(-4, -2)
		C.	(-4, -8)
		D.	Each equation has the same graph, so there are infinitely many solutions.
		Hint
	4.	State whether the graph is consistent and independent, consistent and dependent, or inconsistent.
		A.	consistent and dependent
		B.	consistent and independent
		C.	independent
		D.	none of the these
		Hint
	5.	Katrina has $50 and makes $6 per hour. Kevin has $30 and makes $1 every ten minutes. If neither of them spends any money and they work the same hours, will Katrina and Kevin ever have the same amount of money?
		A.	Kevin will always have more money
		B.	Eventually they will have the same amount of money.
		C.	Katrina will always have more money.
		D.	They will always have the same amount of money.
