a = 3
b = 8
c = 4
So, the expression will become: 
So, the expression that belongs in the box is 8 x 4
Option C is correct answer.
3x+2=x+6
subtract x from both sides,subtract 2 from both sides, gives you 2x=4,then divide by 2 on both sides and x will equal 2. Input the 2 for x and see if it will graph in a straight line on a graph.
