What is the distance, in units, between the points \((-3, -4)\) and \((4, -5)\)? Express your answer in simplest radical form.

(-3, -4)   and  ( 4, -5)......the distance is given by

 

sqrt [ ( -3 - 4)^2 + ( -5 - -4)^2 ]  =

 

sqrt [ ( -7)^2  + (-1)^2 ] =

 

sqrt [ 49 + 1 ] =

 

sqrt [ 50 ]  =

 

sqrt [ 25 * 2 ] =

 

sqrt (25) * sqrt (2)  =

 

5*sqrt (2)

 

 

 

cool cool cool
