Use the distance formula:



Let the given point be

So



One-by-one, substitute the values of the coordinates in the answer choices for and . One of the sets of coordinates will make a true statement.

Hi,
Which of the following points is 5 units away from the point (3, 6)?
D = sqrt%28%283-x%29%5E2+%2B+%286-y%29%5E2%29+=+5
0r
%28%283-x%29%5E2+%2B+%286-y%29%5E2%29+=+25
Trying the different points:
Pt (8,6) ⇒ %28%283-8%29%5E2+%2B+%286-0%29%5E2%29+=+25
