Given points A (-1, 7) and 5(-7, -7), write the vector AB vector in the I. j form.

Solution

Find a and b by subtracting the x and y values for the terminal point minus the initial point

write v in the form ai + bj

For A ( -1 , 7) , B( -7 , - 7 )

then

a = - 7 - ( -1 ) ==> - 7 + 1 ==> -6

b = - 7 - ( 7 ) ==>- 7 - 7 ===> -14

therefore v in i, j is

AB is ===> - 6 i - 14 j
