1. Find the distance between the following pairs of points:
(i) (2, 3), (4,1) (ii) (-5, 7), (-1, 3) (iii) (a, b), (-a, -b)
Note: To find distance between any two given points (
) and (
), we use distance formula:
d =
Solution (i)
Applying Distance Formula to find distance between points (2, 3) and (4,1), we get
d =
Solution (ii)
Applying Distance Formula to find distance between points (-5, 7) and (-1, 3), we get
d =
Solution (iii)
