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
