I am trying to reproduce this image. This is what I have so far but I don't know where to start in putting the arrows on my graph.
All suggestions welcome.

You might either use shapes.arrows or just draw thick lines with arrow heads. The following example illustrates both options.

documentclassarticle
usepackagetikz
usetikzlibraryshapes.arrows,matrix,positioning
begindocument
begintikzpicture[scale=.6,cap=round]

 beginscope[style=axes]
 draw[->] (-7.5,0) -- (7.5,0) node[above] $x$;
 draw[->] (0,-7.5)-- (0,7.5) node[left] $y$;
 foreach x/xtext in -6/-12, -5/-10, -4/-8, -3/-6, -2/-4, 1/2, 2/4, 3/6, 4/8, 5/10, 6/12

 $ytext$;
 filldraw[black] (2,5.5) circle (3pt) node[fill=white,left=3pt] ;
 draw[domain=-4.1:2.9,smooth,variable=x,black,<->,thick] plot (x,.5*(3+4*x));

 approach 11 from the right.
 -- ([xshift=-1mm,yshift=-8mm]mat-2-8.south east);
endtikzpicture
enddocument

BTW, you forgot begindocument and enddocument in your example and it would really help if you provide the table and everything that needs to be typed in the future.

  Marmot, I can not thank you enough!!! I will have to spend quite a bit of time studying this program. Very helpful. I could have created a tabular table but you used a matrix which I never would have thought of. I will note your request in the future.

BTW, you forgot begindocument and enddocument in your example and it would really help if you provide the table and everything that needs to be typed in the future.

  Marmot, I can not thank you enough!!! I will have to spend quite a bit of time studying this program. Very helpful. I could have created a tabular table but you used a matrix which I never would have thought of. I will note your request in the future.

  I will upvote it but I don't know how. I am looking for the field to upvote and I can not find. Please advise I will do it!

You might either use shapes.arrows or just draw thick lines with arrow heads. The following example illustrates both options.

  Marmot, I can not thank you enough!!! I will have to spend quite a bit of time studying this program. Very helpful. I could have created a tabular table but you used a matrix which I never would have thought of. I will note your request in the future.
