Find the terminal point of each of the following vectors. Draw each one as a directed line segment in the [math]xy[/math]-plane, and compute its length.

• [a [math]\vec v = (-3,4)_P[/math], where [math]P = (1,0)[/math],
• [math]\vec u = (4, -3)_P[/math], where [math]P = (1,0)[/math],
• [math]\vec x = (3,0)_Q[/math], where [math]Q = (-1,-1)[/math],
• [math]\vec a = (4\frac12,3\frac12)_O[/math], where [math]O = (0,0)[/math].
