**Reiny**, Tuesday, January 25, 2011 at 12:09pmslope of line through the two points = (6-2)/(3-1) = 2

so the slope of your new line = -1/2

since the slopes must be negative reciprocals of each other.

new equation:

y = (-1/2)x + b

but (2,2) lies on this

2 = (-1/2)(2) + b

3 = b

y = (-1/2)x + 3
