_________________________________________

$Distance \: formula \: = \sqrt{ {(x2 - x1)}^{2} + {(y2 - y1)}^{2} }$

_________________________________________

Given:-

A (1,-3)

B (2,-5)

x1 = 1

x2 = 2

y1 = -3

y2 = -5

______________________________

Proof:-

⇒$\sqrt{ {(2 - 1)}^{2} + { ((- 5) - ( - 3))}^{2} }$

⇒$\sqrt{ {1}^{2} + {( - 2)}^{2} }$

⇒$\sqrt{1 + 4}$

⇒$\sqrt{5}$

Distance is approximately 2.237 units.
