Find the ratio in which the point P(3/4, 5/12) divides the line segments joining the point A(1/2, 3/2) and B(2, -5). |
Answer» Given, Points A(1/2, 3/2) and B(2, -5) Let the point P(3/4, 5/12) divide the line segment AB in the ratio k: 1 Then, we know that P(3/4, 5/12) = (2k + 1/2)/ (k +1) , (2k + 3/2)/ (k + 1) Now, equating the abscissa we get 3/4 = (2k + 1/2)/ (k +1) 3(k + 1) = 4(2k + 1/2) 3k + 3 = 8k + 2 5k = 1 k = 1/5 Therefore, the ratio in which the point P(3/4, 5/12) divides is 1: 5 |
