Question

Determine a distancia dos pontos a(-5,-3) b(-2,-1)

Answer 1

a(-5,-3) b(-2,-1)
        
         _________________
D = V(x2-x1)2 + ( y2 - y1)2
         _________________
D = V(-2-(-5))2 + (-1-(-3))
         ______________
D = V (-2+5)2 + (-1+3)2   
         _________
D = V3^2 + 2^2
         ____                 ___
D = V9+4   ==> D = V13
