Question 774297: points (1,1) and (5,2)lie on k. what is the slope of the line that is perpendicular to k?
Answer by oscargut(2103) (Show Source): You can put this solution on YOUR website!
k has a slope of : (2-1)/(5-1) = 1/4
Then the slope of a line perpendicular to k is: -4
(product of the slopes must be -1)
Answer: -4
