The solution is going to be the point where the two lines on a graph intersect.
Step-by-step explanation:
The solution of a system is going to be a ordered pair that satisfies all of the equations in the system. This translates to the lines intersecting on a graph since they all go through the same ordered pair.
Lets calculate derivative of

That is:

Comparing that with offered answer we can see that results match.
