start with easy and go to harder, if you have to
assume a linear function ... y = m x + b
when x is 0 , y is -1 ... so b is -1
when x is -2 , y is 9 ... 9 = -2 m - 1 ... 10 = -2 m ... m = -5
when x is 2 , y is -11 ... -11 = 2 m - 1 ... -10 = 2 m ... m = -5
looks linear ... y = -5 x - 1 ... check some other points
plz someone help??? I have no Idea how to do this
