Respuesta :

4.7 because if you plug it in- (2,1) and (6,6) it is 4.7 units 
texaschic101
distance formula : sqrt ((x2 - x1)^2 + (y2 - y1)^2)
(2,1)...x1 = 2 and y1 = 1
(6,6)...x2 = 6 and y2 = 6
time to sub and solve :)
d = sqrt ((6 - 2)^2 + (6 - 1)^2)
d = sqrt ((4^2) + (5^2))
d = sqrt (16 + 25)
d = sqrt 41
d = 6.40 <===
