Question

Name a point that is (radical 2) away from (-1,5).

Answer 1

The questions asked to name a particular points that contains x and y coordinates.
distance = (x -(-1))2 + (y -5)2    = 2
distance = (x +1))2 + (y -5)2    = 2
                => (√(2) -1,5)
                =>  (-1, 5 + √ (2)
                => (0, 4)
                => (0, 6)Thus, here are the lists of possible points. (0, 4) and (0, 6).
