Find the distance between the following points:

(i) (–6, 7) and (–1, –5)

(ii) (–1, –1) and (8, –2)

(iii) (at12, 2at1) and (at22, 2at2)

Answer :

We know that distance between two points (x1, y1) and (x2, y2) is given by


(i) Let the points (–6, 7) and (–1, –5) be A and B respectively, so the distance between them






(ii) Let the points (–1, –1) and (8, –2) be A and B respectively, so the distance between them






(iii) Let the points (at12, 2at1) and (at22, 2at2) be A and B respectively, so the distance between them
