Option Top-Left -> Doesn't work because there are two y-values at the x-value 0.
Option Top-Right -> Doesn't work because there are two y-values at the x-values -2 and 2.
Option Bottom-Left -> Doesn't work because there are two y-values at the x-values -1.
Option Bottom-Right -> Works because for every y-value, there is only one x-value.
