Question

1. Find the coordinates of the point which divides the join of(-1,7) and (4, -3) in the ratio
2:3.​

Answer 1

Answer:

m=2 and n=3

X1= -1 and x2=4

y1=7 and y2=-3

2× then:- x= (mx2+nx1)/m+n

= (2×4+3×-1)/2+3

=(8-3)/5

=5/5=1

y=(my2+ny1)/m+n

= (2×-3+3×7)/2+3

= (-6+21)/5

= 15/5=3

hence coordinate is (1,3)
