Question

Determime the ratio in which point l(2and 1) divides the line joining point of a(-6 and 4) b (1 and -3) find value of l

Answer 1

Section Formula;

x = ( mx2+nx1 )/ ( m+n )

y = ( my2 + ny1 )/ ( m+n )

1 = (-m*3 +n*4)/(m+n)

m + n = -3m + 4n

4m - 3n = 0

4m = 3n

m/n = 3/4

m:n = 3:4

Ratio = 3:4
