If line g passes through point (2, 2) and is perpendicular to the line h, then what is the equation of line g? With h passing through two points (1, 2) and (3, 6)

slope of line through the two points = (62)/(31) = 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
