What are the coordinates of the point on the directed line segment from ( − 10 , 9 ) (−10,9) to ( 8 , − 9 ) (8,−9) that partitions the segment into a ratio of 1 to 2?

Answer:

(-4,3) is the point that divides the line segment in 1:2

Step-by-step explanation:

Given line segment whose coordinates are (-10,9) and (8,-9)  that partitioned the line segment in ratio 1:2 . we have to find out the coordinates of points that divides the line segment in 1:2

By internal section formula, coordinates of point C which divides the line segment in m:n will be

[tex][\frac{(mx_{2}+nx_{1})}{(m+n)},\frac{(mx_{2}+nx_{1})}{(m+n)}][/tex]

Here,  [tex]m=1, n=2, x_{1}=-10, x_{2}=8, y_{1}=9, y_{2}=-9[/tex]

∴ Coordinates of point C are [tex][\frac{1(8)+2(-10)}{(1+2)}, \frac{1(-9)+2(9)}{(1+2)}][/tex]

⇒ [tex](\frac{-12}{3}, \frac{9}{3})=(-4,3)[/tex]

Hence, (-4,3) is the point that divides the line segment in 1:2
