Question

Find the co ordinates of a point which divides the line joining the points (-3,1)and(9,3) internally in the ratio 1:3.​

Answer 1

Answer:

(0,3/2)

Step-by-step explanation:

x1=-3;y1=1;x2=9;y2=3;m=1;n=3

x=mx2+nx1/m+n

x=1(9)+3(-3)/1+3

x=9-9/4

x=0/4

x=0

y=my2+ny1/m+n

y=1(3)+3(1)/3+1

y=3+3/4

y=6/4

y=3/2

the co-ordinate of point which divide the line joining the point is (0,3/2)
