The total number of chairs y varies directly with the number of tables x, as shown in the graph. Write a direct variation equation to represent this relationship. Then identify the constant of variation and interpret its meaning.

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
