14)  if  AB = CB then i can solve as

< ABC = <CBA = 42

<ABC = 84

in triangle ABC 

<ACB = <CAB

2<CAB + 84 = 180

<CAB = 96/2 = 48

15)     (x + 4)^2 + (y + 4)^2 = 4^2

  (x + 4)^2 + (y + 4)^2 = 16

16)     (x + 3)^2 + (y - 5)^2 = (5/2)^2

    (x + 3)^2 + (y - 5)^2 = 25/4

17)   center at (4 , - 3) & radius = 5

circle will pass through (- 1 , - 3)  ,  (9 , - 3)  , 94 , 2) & ( 4 , - 8)

coordinates of intercepts (0 , 0) , (8 , 0) , (0 , 6)

18)   center = (2 , - 1)

y-intercept (0 , 2) & (0 , - 4)

if you want graph post as paid question .

hope this will help you .
