Question

find the distance between the following points (3,-2) and (-7,5) ​

Answer 1

Take points A(3,-2) and B=(-7,5)

TO FIND THE DISTANCE BETWEEN TWO FORMULAS WE USE DISTANCE FORMULA...

which is

$ab = \sqrt{ {( x_{1} - x_{2}) }^{2} } + ( y_{1} - y_{2} {) {} }^{2}$

$so \: ab \: = \sqrt{( -3 - 2{)}^{2} } + ( - 7 - 5 {)}^{2} = \sqrt{25 + 144} = \sqrt{169} = 13$

hope it's helps you ❤️

have a great day ❣️☺️
