Question

Find the distance between the two points in simplest radical form. (8,−8) and (−1,−5)

Answer 1

Answer:

Solution given:

$x_{1},y_{1}=(8,-8)$

$x_{2},y_{2}=(-1,-5)$

Now

Distance between them is:

d=$\sqrt{(x_{2}-x_{1})²+(y_{2}-y_{1})²}$

d=$\sqrt{(-1-8)²+(-5+8)²}=3\sqrt{10}$

Distance between them is $\bold{3\sqrt{10}}$
