Answer:
Therefore the co-ordinate of the point on the line segment from (-9,-1) to(-9,-10) into a ratio internally is (-9,-7).
Therefore the co-ordinate of the point on the line segment from (-9,-1) to(-9,-10) into a ratio internally is (-9,-19).
Step-by-step explanation:
Given points are (-9,-1) and (-9,-10)
If a point divides the line segment by joining two points (x₁,y₁) and (x₂,y₂) into a ratio m:n internally.
Then the point of the coordinate is .
If a line segment is externally divided into a point by joining two points (x₁,y₁) and (x₂,y₂) with m: n ratio.
Then the point of the coordinate is .
Internally
The co-ordinate of the point is
Externally
The co-ordinate of the point is
= (-9,-19)
