Title: Fix bug: Limit answer range

The exercise previously could include quite a range of answers (slope of 99 or even greater), and with the current button-style entry method, this would take forever to input. Changed range to -10 < M < 10 and -10 < B < 10 for the slope and y-intercept, respectively.
