No, because in the first one the 4 is negative, in the second it is positive
x y
------ -----
-9 -2
-5 -7
-1 -12
3 -17
ur x's all have a difference of 4, and ur y's all have a difference of -5...so yes, this is linear with a slope of (-7+2) / (-5 + 9) = -5/4
The answer is 12 because you have to subtract
32-20
