A) 18.86 units
B) 19 units
C) 22 units
D) 25.25 units
Correct Answer: A
$ \therefore $ $ x _1=-6, $ $ y _1=8, $ $ x _2=4 $ and $ y _2=-8 $
$ \therefore $ Required distance, $ AB=\sqrt{{{(x _2-x _1)}^{2}}+{{(y _2-y _1)}^{2}}} $ $ =\sqrt{{{(4+6)}^{2}}+{{(-16)}^{2}}}=\sqrt{100+256} $ $ =\sqrt{356}=18.86units $
