Question

Let u= <6,-9>, v=<1,-4>. Find u-v

Answer 1

I think its 5,-5

Answer 2

\[\vec u = \langle a_1~,~a_2\rangle = \langle 6~,~-9\rangle \]\[\vec v = \langle b_1~,~b_2\rangle = \langle 1~,~-4\rangle \]\[\vec u - \vec v = \langle a_1-b_1~,~a_2-b_2\rangle = \langle 6-1~,~ -9-(-4)\rangle = \langle 5~,~ -5\rangle ~\checkmark\]
