Best answer 16 votes 16 votes For two points $(x_1,y_1)$ and $(x_2,y_2)$ on a line, Slope of line $= \dfrac{y_2-y_1}{x_2-x_1}$ so ,$\dfrac{q-p}{0-4} = \dfrac{3}{4}$ $\therefore (p-q)=3$ Correct Answer: $C$ Praveen Saini answered Feb 29, 2016 • edited Apr 25, 2019 by Naveen Kumar 3 Praveen Saini comment Share Follow See all 0 reply Please log in or register to add a comment.
