Find the ratio in which the Y axis divides the line segment joining the points (5,-6)and (-1,-4) |
| Answer» Let y-axis divides the line segment joining the points(5, - 6) and (- 1, - 4) in the ratio k: 1and the coordinates of the required point be (0, y).Then, 0 =\xa0{tex}\\frac { 5 \\times ( 1 ) + k \\times ( - 1 ) } { k + 1 }{/tex}{tex}\\Rightarrow{/tex}\xa05 - k = 0{tex}\\Rightarrow{/tex}\xa0k = 5Thus, y-axis divides the line segment joining the points (- 5 , 6) and (- 1, -4) in the ratio 5 : 1. | |
