The point is

EXPLANATION
When two nonparallel lines are drawn on the same plane, they will intersect at a unique point. This point represents the solution to the two systems of equations represented by the lines.
The vertical line

and the horizontal line

will intersect at

This is the unique solution to the two equations.

Well for the small box of Cornflakes you want to divide $6.30 by 18 and you should get $0.35 which is how much each oz cost.
For the large box you want to convert 2.2 lb to oz, you will get 35.2 oz. Next just do the same divide $8.80 by 35.2 and get $0.25 which is the cost for each oz in the large box.
