Find the distance between the points:
A(1, – 3) and B(4, – 6)
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 = √{(4 – 1)2 + (– 6 – (– 3))2}
= √{(3)2 + (– 3)2}
= √{9 + 9}
= √18
∴ AB = 3√2 units
