A) \[\left( \frac{22}{3},\,\frac{11}{3} \right)\]
B) \[\left( \frac{28}{3},\,\frac{14}{3} \right)\]
C) \[\left( 6,\,1 \right)\]
D) \[\left( 9,\,1 \right)\]
Correct Answer: B
Solution :
Let the coordinates of I be (x, y) |
By section formula, |
\[x=\frac{1\times 10+2\times 9}{1+2}=\frac{10+18}{3}=\frac{28}{3}\] |
\[y=\frac{1\times 6+2\times 4}{1+2}=\frac{6+8}{3}=\frac{14}{3}\] |
Hence, the coordinates of I is |
\[\left( \frac{28}{3},\,\frac{14}{3} \right)\] |
