the answer is b) 4^2 + 7^2
proof 
(3.-5) - (-1.2) = (4. -7), the length of vectAB((4. -7) =sqrt (4^2 + 7^2)

Answer:   4²+7²

Step-by-step explanation:

since length of line segment (x1,y1) and (x2,y2) is given by

        \(\sqrt{(x1-x2)^2+(y1-y2)^2}\)

here (x1,y1)=(3,-5) and (x2,y2)=(-1,2)

hernce length =  \(\sqrt{(3-(-1))^2+(-5-2)^2}\)

                        =  \(\sqrt{(4)^2+(7)^2}\)
