1.	What is the final answer to this Think of a Number trick? Think of a number. Subtract 6. Multiply by –3. Subtract 18.
		A.	the answer is 3 times the number you started with
		B.	the answer is 1.5 times the number you started with
		C.	the answer is –1.5 times the number you started with
		D.	the answer is –3 times the number you started with
		Hint
	2.	Simplify the equation.y = –2(x – 7) – (9 + 5x)
		A.	y = –7x + 5	B.	y = 7x – 5
		C.	y = –16x + 3	D.	y = 3x – 16
		Hint
	3.	Which equation is not linear?
		A.	y = –2(–8 – x) – 5x (x – 1)
		B.	5x – 2y = 4.1
		C.	–3y + x – 16 + 2.9x= 0
		D.
		Hint
	4.	Which equation is not the same as the other three?
		A.	6 + 2y = x	B.
		C.		D.
		Hint
	5.	Name a similarity and a difference among the three graphs below. 7x + y + 8 = 0 –7x + y + 8 = 0 –3x – y – 8 = 0
		A.	The graphs have the same y-intercept, but different slopes.
		B.	The graphs have the same slope and y-intercept.
		C.	None of the graphs have the same slope nor the same y-intercept.
		D.	The graphs have the same slope, but different y-intercepts.
