		B.	the answer is 2 more than the number you started with
		C.	the answer is –2 times the number you started with
		D.	the answer is 2 less than the number you started with
		Hint
	2.	Find the linear equation.
		A.	y = 7x (x– 1) + 4(9.6 –x)
		B.	y = 10(x – 8) + 3x2
		C.	y = 5.2(x – 6) – 2(4 – 3x)
		D.	y = x + x2 – 7x + 4.9
		Hint
