Question

The distance between the points $A(-6,7)$ and $B(-1,-5)$ is.

• A. 13 units
• B. 14 units
• C. 15 units
• D. none of these

Answer 1

Answer: (A)

13 units

The distance between points $A(-6,7)$ and $B(1,-5)$

The distance between the points $d=\sqrt{{(x}_2-x_1{)}^2+(-{y_2-y_1)}^2}$

$\therefore AB=\sqrt{(-1+6{)}^2+(-5-7{)}^2}$

$=\sqrt{25+144}$
$=\sqrt{169}$

$=13$ sq. units
