How can graphing be applied to solving systems of non-linear equations?
how can constraints be used to model a real-world situation?

if we are given a system of non-linear equations than we can plot the graph of the system of equations in the coordinate plane and depending on the sign of the inequality shade the region. and see the intersection region to obtain the feasible region and also the intersection point of the two plane in order to obtain a optimal solution. Constraints play a vital role in the real-world situation.

For example: we are given a cost of 1 pencil and one pen and we are given the maximum amount one has: then this problem could be modeled by the inequalities.

The question is asking to states on how can graphing be applied to solving systems of non-linear equation, and base on my research, I would say that when you have non linear equation and plot them, you can obtains the points where those function intersect, so they are possible solution. Constraints could be use as guide line or model.
