Find ratio line segment joining A (1,-5) and B (-4,5) x axis |
|
Answer» ong>Answer: Let the point on X-axis be P (x,0) since the y-coordinate is always zero on x - axis. Given A(1, -3) and B(4,5) Let P divides the LINE joining the given points (1, -3) and (4, 5) in the RATIO m : 1. The COORDINATES of P = (mx2 + x1 / m +1 , my2 + y1 / m + 1) i.e. (x, 0 ) = ( 4m +1/ m+1 , 5m -3/ m+1) By comparing both the sides, we get. 5m -3 ...
