Slope of the side DA of the rectangle ABCD is -3/4. What is the slope of the side AB?
Side DA and AB in the rectangle ABCD are perpendicular to each other, and product of slopes of two perpendicular lines is -1
Let slope of AB = $$m$$ and slope of DA = -3/4
=> $$m \times \frac{-3}{4}=-1$$
=> $$m = \frac{4}{3}$$
=> Ans - (D)
