In what ratio does the point (a, 6) divide the join of (-4, 3) and (2, 8)? Also, find the value of a.
Let the point P (a, 6) divides the line segment joining A (-4, 3) and B (2, 8) in the ratio k: 1.
Using section formula, we have:
`=>a=(2xx3/2-4)/(3/2+1)` (from equation 1)
Hence, the required ratio is 3:2 and the value of a is `-2/5`
