We know that the line is tangent at the point (2,8)
The derivative of the function at x=2 is
So, the tangent line passes through the point (2,8) and has slope 2. The equation is
This line crosses the x axis where y=0:

Given:
The equations of system of equations are
To find:
The solution of given system of equations.
Solution:
We have,
...(i)
...(ii)
Adding y on both sides in (ii), we get
It is same as equation (i). So, we can say that equation (i) and (ii) represent the same line or they are coincident.
Thus, the system of equations has infinitely many solutions.
Therefore, the correct option is C.
