 Question 529742: Is the line through points P(–8, –10) and Q(–5, –12) perpendicular to the line through points R(9, –6) and S(17, –5)? Explain.Answer by solver91311(16897)   (Show Source): You can put this solution on YOUR website! Use the slope formula where and are the coordinates of the given points P and Q. Then do it again for points R and S. If the slope of the line through P and Q is the negative reciprocal of the slope of the line through R and S, then the lines are perpendicular. Otherwise, not.
