Question

The distance between the points (-1,3) and (2,-1) is?

Answer 1

It is 5.83 units

Explanation:

`{ \bf{length = \sqrt{ {(x_(1) - x _(2) ) }^(2) + {(y _(1) - y_(2))}^(2) } }}`

x1 is -1

x2 is 2

y1 is 3

y2 is -1

`= \sqrt{ {( - 1 - 2)}^(2) + { \{3 - ( - 2) \}}^(2) } \\ \\ = √(9 + 25) \\ = √(34)`
