Question 46
What is the slope of the line perpendicular to the line passing through the points (6,3) and (2,7)?
Solution
Slope of line passing through points (6,3) and (2,7)
= $$\frac{7 - 3}{2-6} = \frac{4}{-4} = -1$$
Product of slopes of two perpendicular lines is -1
=> Slope of the line perpendicular to the line having slope -1 = $$1$$
=> Ans - (A)
