The solution to the problem is reduced to finding M. Since the graph of the linear function y = 2x + M passes through the point A (-1; 5), substituting its coordinates into the function, we get the correct equality.
5 = 2 * (-1) + M
Solving this equation, we find the value of M.
-2 + M = 5
M = 5 + 2
M = 7
Answer: y = 2x + 7.
