Some formatting changes.

Changed part c, because I'm not sure what it was asking for is possible. It said, "if $x_i-\bar{x}$ increases for every i, what happens to b?"

$x_i - \bar{x}$ can't increase for every i, because the mean would move.

You could say $\lvert x_i - \bar{x} \rvert$ increases, but that's getting a bit complicated. You would never think about things this way, anyway.
