3.6 Practice B

Error in answer file. Under construction.

1)   -  3 / 5    2)  3 / 5    3)  5 / 0 so slope is UNDEFINED

4)  slope of AB is 2 / 5   and slope of CD is 2 / 5

5) slope of AB is - 3 / 1  and slope of DC is  - 6 / 1

6) slope of AB is  - 2 / 2  =  -1   and slope of CD is  - 5 / 5 =  -1

7)  y =  2x  -3               8) y = -3x  +  1/3        9)  y = 1 / 2 x  + 6

10)  y = 2x  + 5      11)  y =  4/5x + 2       12)  y  = -1x - 6

13)

14    slope of AB = 9 / 1      slope   of  CD  = 9 / 1       slope of CB  = - 1 /  2        slope  DA  =  - 1 / 2

15.  Yes,   the two pairs of opposite sides are parallel and therefore the shape ABCD is a parallelogram
