I have another problem. I am given a real number line with the two points -3 an 1 marked on it. How do I write an absolute value equations from this data?

If $\displaystyle a<b$ then the equation $\displaystyle \left| {x - \frac{{b + a}}{2}} \right| = \frac{{b - a}}{2}$ has solutions $\displaystyle x=a\text{ or }x=b$.
No, plugging and chugging is quite simple. But I have never seen that formula you have presented me with. Also, the way the book wants me to solve it is just graphically.
