Answer 2

Here x¹ = -3, y¹ = 10, x² = 6, y² = -8

[m(6) + n (-3)]/(m+n), [m(-8) + n (10)]/(m+n) = (-1, 6)

(6m - 3n)/(m+n), (-8m+10n)/(m+n) = (-1, 6)

equating the coefficients of x and y

(6m-3n)/(m+n) = -1

(-8m+10n)/(m+n) = 6

6m - 3n = -1 (m+n)

6m - 3n = -1 (m+n)

6m-3n=-m-n

6m+m=-n+3n

7m=2n

m/n= 2/7

m:n = 2:7

So the point (-1, 6) is dividing the line segment in the ratio 2:7.
