Answers to MTH-075 Practice Test #2

No students asked for the answers, but here they are anyway.

1) 3(-4)+5(2)=-2? yes

2) B

3) (0, -4),(4, 0),(8,4) (Then plot these points and draw a straight line though them.)

4) (0, -3),(3,3),(-3,-9) (Then plot these points and draw a straight line though them.)

5) A

6) Make an x|y table and fill in at least two points in it. Easiest are the intercepts, (4,0) and (0,4). Then plot these points and draw a straight line though them.

7) Ditto, except the intercepts are (0,4) and (-8,0).

8) Vertical line through x=3.

9) You don't need help with this, I hope!

10) -7/6

11) 0

12) B

13) C

14) A

15) C

16) y = (5/2)x - 2

17) y = (3/4)x

18) Dashed horizontal line through y = 4, everything below it shaded.

19) Solid diagonal line through the origin with slope of 3, everything to the left of it shaded.

20) Solid diagonal line through the points (0, 4) and (3, 0), everything to the left of it shaded.

MTH-075 Practice Test #1 (now with answers) and Test Announcement

Unit Test #1 will be in class on Wednesday, February 15. It will cover Chapter 2.

The practice test is below. To get the most out of it, print it out and do the problems on your own. Then bring it to class with you on Monday, February 13. We will have a review session then, based on the practice test.

(Note: One student showed me how Docstoc demanded payment and asked for credit card info when she attempted to download this. This happened in the computer lab at Willingboro using Internet Explorer, and may have to do with the version of Flash or a network security issue at BCC. I just tried it at home (Monday 2/13 6pm) and it works fine with both IE and Firefox, so the problem is with BCC. If you have any trouble, email me and let me know.)
