Example Question #3 : Vector Components: Ccss.Math.Content.Hsn Vm.A.2

What are the components of a vector that has a terminal point of \displaystyle (1,1) , and an initial point of \displaystyle (-6,-9)?

Possible Answers:

\displaystyle < 7,10>

\displaystyle < -10,-7>

\displaystyle < -7,-10>

\displaystyle < 10,7>

\displaystyle < 0,0>

Correct answer:

\displaystyle < 7,10>

Explanation:

In order to determine what the components of this vector has, we need to remember how to find components of a vector. It's simply the difference between the terminal point and initial point. The first step is to write an equation for what our "new" x and y are. 

\displaystyle x=\mbox{(x in terminal point)}-\mbox{(x in initial point) }

\displaystyle y=\mbox{(y in terminal point)}-\mbox{(y in initial point) }

Now lets identify what these values are.

\displaystyle \\ \mbox{(x in terminal point)}=1 \\ \mbox{(x in initial point)}=-6 \\ \mbox{(y in terminal point)}=1\\ \mbox{(y in initial point)}= -9

\displaystyle x=1-(-6)=1+6=7

\displaystyle y=1-(-9)=1+9=10

To write this in component form, we need to put our \displaystyle x, and \displaystyle y into \displaystyle < >.

So the final answer is \displaystyle < 7,10>

\displaystyle < 14,-11>

\displaystyle < 11,14>

\displaystyle < -14,11>

Correct answer:

\displaystyle < -14,11>

Explanation:

In order to determine what the components of this vector has, we need to remember how to find components of a vector. It's simply the difference between the terminal point and initial point. The first step is to write an equation for what our "new" x and y are. 

\displaystyle x=\mbox{(x in terminal point)}-\mbox{(x in initial point) }

\displaystyle y=\mbox{(y in terminal point)}-\mbox{(y in initial point) }

Now lets identify what these values are.

\displaystyle \\ \mbox{(x in terminal point)}=-9 \\ \mbox{(x in initial point)}=2 \\ \mbox{(y in terminal point)}=1\\ \mbox{(y in initial point)}= -10
