In what ratio does the point (-4, 6) divides the line segment joining the points (-6, 10) and (3, -8)? |
1 : 7 3 : 4 1 : 4 2 : 7 |
2 : 7 |
Coordinates of end points are (-6, 10) and (3, -8) Point that divides the line segment is of coordinates ( -4, 6 ) Lets us consider that , Desired ration = m : n According to question , - 4 = \(\frac{ 3 ×m + n × (-6)}{m + n }\) -4m -4n = 3m - 6n 2n = 7m \(\frac{m}{n}\) = \(\frac{2}{7}\) So, m : n = 2 : 7 |
