Question 465936
The slope of the line joining(1, 0) and (5, -2) is {{{(-2 - 0)/(5 - 1) = -2/4 = -1/2}}}.  the perpendicular slope is then the negative reciprocal, which is 2.

The midpoint between (1, 0) and (5, -2) is (3, - 1).  

The equation of the line is then

y - -1 = 2(x - 3),
<==> y+1 = 2x - 6, or 2x - y = 7, or 2x - y - 7 = 0, whatever your fancy is.
