Answer:
Partitioning a line segment, AB, into a ratio a/b involves dividing the line segment into a + b equal parts and finding a point that is a equal parts from A and b equal parts from B. When finding a point, P, to partition a line segment, AB, into the ratio a/b, we first find a ratio c = a / (a + b).

HOPE IT HELPS AND MARK AS BRAINLIEST PLEASE FOLLOW ME.❤️
Step-by-step explanation:
Using section formula:
a=(m*4+n*(-5) )/(m+n)......eqn 1.
7=(m*10+n*6)/(m+n)......eqn 2.
solving 2:
7m+7n=10m+6n
3m=n
m/n=1/3.
Ratio=1/3.
eqn 1:
a=(4m-5n)/(m+n)
use n=3m here.
a=(4m-5(3m))/(m+3m)
a=-11/4.
done.
