• Question:

Given three points M(2; 2), N( – 4; – 4), P(5; 5). Which of the following assertion true?

Reference explanation:

Correct answer: A

We have: $$\overrightarrow {MN} \left( { – 6; – 6} \right);\,\overrightarrow {MP} \left( {3;3} \right)$$.

Derive: $$\overrightarrow {MN} = – 2\overrightarrow {MP}$$.

The two vectors $$\overrightarrow {MN} ;\overrightarrow {MP}$$ are in opposite directions so M lies between N and P .

Answer A
