Please check my work:
Jo was working with several friends on precalculus homework. The item asked for them to find the magnitude of the vector graphed. Jo noticed that each person had set up the formula to find the magnitude differently. Who is correct? Select all that apply. (2 correct answers)

A.) Kari’s Work: ||v||= √((6)^2 + (-2)^2)<---- I think it is this one

B.) Tia’s Work: ||v|| = √((1-7)^2 + (3-1)^2)

C.) Abe’s Work: ||v|| = √((7-1)^2 + (1-3)^2)

D.) Mike’s Work: ||v|| = √((-6)^2 + (2)^2)

E.) Sam’s Work: ||v|| = √((6)^2 + (2)^2)<----- as well as this one
