Answer :

apologiabiology
for points (x1,y1) and (x2,y2)
D=[tex] \sqrt{(x2-x1)^2+(y2-y1)^2} [/tex]

(-5,5)
(1,-3)
(x,y)
x1=-5
y1=5
x2=1
y2=-3

D=[tex] \sqrt{(x2-x1)^2+(y2-y1)^2} [/tex]
D=[tex] \sqrt{(1-(-5))^2+(-3-5)^2} [/tex]
D=[tex] \sqrt{(6)^2+(-8)^2} [/tex]
D=[tex] \sqrt{36+64} [/tex]
D=[tex] \sqrt{100} [/tex]
D=10
