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)
