19
(18 x 9) - (19 x 8) = 10
18/20=9/10
Points: (-18, -7) and (-20-9) Slope works out as 1
18
Points: (2, -2) and (1, 9) Slope: -11
9 - (-10) = 9 + 10 = 19
9 plus 10 = 19
3 9 19 - 51DIFF: 6 10 14 1851-18=33Answer is 33.
Well whats x. if x=19, then you do 19-1 ____ 9 19-1=18 18 __ = 18/9= 18 divided by 9 = 2. 9 it all depends on x

1 + 18 = 19, 2 + 17 = 19, etc. 10 + 9 = 21 correct
