Q=(3.6,1.4)
Step By Step:
A point Q on a segment with endpoints A (2, −1) and C (4, 2) partitions the segment in a 4:1 ratio.
A=(x_1,y_1)=(2,-1)
B=(x_2,y_2)=(4,2)
m:n = 4:1
Let (x,y) be the coordinates of Q
Section formula : x=mx_2+nx_1/m+n, y=my_2+ny_1/m+n
Substitute the values in the formula:
x=4(4)+2/4+1, y=4(2)-1/4+1
x=18/5,y=7/5
x=3.6, y=1.4
Hence Q=(3.6,1.4)
