write the ordered pair that represents the vector from A(0,-8) to B(-1,7) then find the magnitude of AB

May 1st, 2015

ordered pair of the vector from A(0,-8) to B(-1,7) is

             =(-1-(0),7-(-8) )

             =(-1,15)

magnitude of |AB| = sqrt((-1)^2 +15^2)

                             =sqrt(1+225)

                             =sqrt(226)

                             =15.03
