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.
