To find the projection of &lt;b&gt;u&lt;/b&gt; onto &lt;b&gt;v&lt;/b&gt;,
which is denoted:

proj&lt;sub&gt;v&lt;/sub&gt;&lt;b&gt;u&lt;/b&gt; ,

1.  Get their dot product:  &lt;b&gt;u•v&lt;/b&gt; 

2.  Divide that by &amp;#8741;&lt;b&gt;v&lt;/b&gt;&amp;#8741;&lt;sup&gt;2&lt;/sup&gt;

3.  Multiply by &lt;b&gt;v&lt;/b&gt;

-------------------------  

1.  Get their dot product:

&lt;-1,7&gt;•&lt;6,4&gt; = (-1)(6)+(7)(4) = -6+28 = 22

2.  Calculate &amp;#8741;&lt;b&gt;v&lt;/b&gt;&amp;#8741;&lt;sup&gt;2&lt;/sup&gt; = &amp;#8741;&lt;6,4&gt;&amp;#8741;&lt;sup&gt;2&lt;/sup&gt; = 6&lt;sup&gt;2&lt;/sup&gt;+4&lt;sup&gt;2&lt;/sup&gt; = 36+16 = 52

Divide 22 by 52  {{{22/52=11/26}}}

3.  Multiply by &lt;b&gt;v&lt;/b&gt;.  {{{11/26}}}&lt;6,4&gt; = &lt;{{{33/13}}},{{{22/13}}}&gt; 

Choice A)
