Question

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

Answer 1

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=
`√((-1-8)²+(-5+8)²)=3√(10)`

Distance between them is
`\bold{3√(10)}`
