MCQ
The distance between $A (-6, 7)$ and $B (-1, -5)$ is:
- A$12$
- ✓$13$
- C$7$
- D$\sqrt{37}$
✓
Answer
Correct option: B.
$13$
Distance between $A$ and $B$ is given by
$\mid\text{A-B}\mid\mid\text{AB}\mid^{2}$
$= (-6+1)^{2}+(5+7)^{2}$
$= 25+144$
$=169$
Then $\mid\text{A - B}\mid = 13$
$\mid\text{A-B}\mid\mid\text{AB}\mid^{2}$
$= (-6+1)^{2}+(5+7)^{2}$
$= 25+144$
$=169$
Then $\mid\text{A - B}\mid = 13$
