Final review

Find the magnitude.

For vectors $$\overrightarrow{AB}$$  and  $$\overrightarrow{CD}$$ , determine if they have the same magnitude, and whether they are parallel.
A(11, -11) and B(8, -4) 
C(5, 2) and D(12, -1)
Select all that apply.

A vector is a quantity that has both _______ and _________.

Select all that apply.

Add

$$<5,\ -2>+<-4,\ 8>$$  

$$a\cdot\overrightarrow{w}\ =\ <a\cdot x,\ a\cdot y>$$   When multiplying a scalar to a vector, you must multiply the scalar number to BOTH the horizontal component AND the vertical component

Given an initial point R ( -12, 4 ) and terminal point S ( 28, -17 ), find the component form of the vector RS. Hint: get it into the pointy brackets.
