Q47 of 149 Page 14

If A (3, y) is equidistant from points P (8, -3) and Q (7,6) , find the value of y and find the distance AQ.

Coordinates are P(8, -3) and Q(7,6)


The point A (3, y) is equidistant.


Using distance formula =


⇒ PA = QA



On squaring both sides, we get


=


=


= 1


AQ = = = units
