Slope of the side DA of the rectangle ABCD is 5/3. What is the slope of the side AB?
Sides DA and AB are perpendicular to each other and product of slopes of two perpendicular lines = -1
Let slope of side AB = $$m$$ an slope of side DA = $$\frac{5}{3}$$
=> $$m \times \frac{5}{3} = -1$$
=> $$m = \frac{-3}{5}$$
=> Ans - (D)
