Question

in what ratio does the point C (- 1, -1) divides the line segment joining the points A(4,4) and B(7,7)

Answer 1

ANSWER:Suppose the point C(-1, -1) divides the line joining the points A(4, 4) and B(7, 7) in the ratio k : 1 Then, the coordinates of C are (7k+4/k+1,7k+4/k+1) But, we are given that the coordinates of the points C are (-1, -1). So, 7k+4/k+1=-1=>k=-5/8 Thus, C divides AB externally in the ratio 5 : 8.Read more on Sarthaks.com - https://www.sarthaks.com/256194/in-which-ratio-does-the-point-1-1-divides-the-line-segment-joining-the-pints-4-4-and-7-7
