Find the scalar and vector components of the vector with initial point `(2,1)` and terminal point `(-5,7)`.

Explanation

Vector with initial point A(2,1) and final (terminal) point B (-5,7) can be given by `AB=(x_2-x_1) hat(i) +(y_2-y_1) hat(j)=(-5-2)hat(i)+(7-1)hat(i)=(-7)hat(i)+6 hat(j)`.
Hence , the required scalar components (coefficients of `hat(i) and hat(j)` are -7 and 6 while the vector components are `-7hat(i) and 6 hat(i)`.
