Answer: the vertex is (12,−144)
Step-by-step explanation:
To solve the problem, simply plug in the value for x in both functions, as shown below:

--> 
---> 

--> 
---> 
----> 
, so the answer is 34.
Y = -6x + 2 . . . . . . . . (1)
-12x - 2y = -4 . . . . . . (2)
Putting (1) into (2), we have
-12x - 2(-6x + 2) = -4
-12x + 12x - 4 = -4
-4 = -4
Therefore, the system has infinite number of solutions.
