Perpendicular

Question

Find the equation of a line perpendicular to the line g(x) =-.01x +2.01 through the point (1,2)

Answer 1

Since perpendicular lines have slopes that are negative reciprocals (i.e. the product of their slopes equals -1), you can figure out ther slope of the desired ⊥ line.  Then use Point Slope form to obtain the answer.
