Which function shares at least one point with the function represented by the equation y=2x

We have the following function:
 y = 2x
 We consider the following function:
 y = x
 Let's evaluate both functions for x = 0
 y = 2x
 y = 2 (0)
 y = 0
 On the other hand:
 y = x
 y = 0
 We observe that the value of y is the same.
 Therefore, both functions have in common the point (0, 0)
 
 A function that shares at least one point with the function represented by the equation y = 2x is:
 y = x
 point (0, 0)
