Answer :

In this question, we have to use the distance formula to find the distance between two points which is given by, say for points P(x1,x2) and Q(y1,y2) then


PQ = √(x2 – x1)2 + (y2 – y1)2



AB = √{(9 – (– 6))2 + (– 12 – (– 4))2}


= √{(15)2 + (– 8)2}


= √{225 + 64}


= √289


AB = 17 units
