Answer :

According to the question,

Distance between AB = 9


Coordinates of A ( - 3, - 14)


Coordinates of B (a, - 5)


Distance between two points (x1, y1) and (x2, y2);


d =



So,


AB = = 9


AB = = 9


On squaring both the sides,


We get;


(a + 3)2 + 81 = 81


(a + 3)2 = 0


A = - 3


Hence, the value of a is - 3.
