Finding perpendicular bisector of the line segement joining $ (-1,4)\;\text{and}\;(3,-2)$ 
Find the perpendicular bisector of the line joining the points $(-1,4)\;\text{and}\;(3,-2).\;$

I know this is a very easy question, and the answer is an equation. So any hints would be very nice. thanks

Hint: The line must be orthogonal to the difference vector $(3-(-1),-2-4)$ and pass through the midpoint $(\frac{-1+3}2,\frac{4-2}2)$.
