I finished the test a while back. I hope this helps anyone.
1: yes; y = 1.625x
2: no; y does not vary directly with x
3: y = 1/3x - 6 Graph: D
4: -4x + 6y = 24 Graph: A
5: 46/1; your car travels 46 miles in 1 hour
6: 1/4
7: -1/2
8: undefined
9: y - 3 = 5(x - 8)
10: y + 6 = -5/8(x + 10)
11: y - 18 = 9(x - 2)
12: x = -5 Graph: A
13: 3x + 4y = 12
14: y = 3x + 4
15: perpendicular
17: y - 3 = -3/8(x +2)
18: The functions have the same shape. the y-intercept of y = x is 0, and the y-intercept of the second function is -5.
19: the two graphs have the same shape, but the seond graph is shifted 5 units left.
20: y = x - 2 Graph: C
21: y + x - 4 Graph: B
22: negative correlation
23: Wouldn't be confident.(you should probably write why you wouldnt be in the paragraph too.)
24: y=0.11(22)+4.45=6.96
Remember that the questions are always changing. So, be sure the look closely at my wording and the wording of your questions to make sure it's the correct answers for YOUR test. That's also the exact reason why I put in the actual answers and not: "C, D, D-etc.". Good luck, everybody!
