Which one of the following options is true, and why?

In the given two variable, if we put the value of x, then we get the corresponding value of y.
if value of x = 0 then ⇒ y = 3 × 0 + 5 ⇒ y = 5
if value of x = 1 then ⇒ y = 3 × 1 + 5 ⇒ y = 8
if value of x = 2 then ⇒ y = 3 × 2 + 5 ⇒ y = 11
if value of x = 12851 then ⇒ y = 3 × 12851 + 5 ⇒ y = 38558
Hence, all these pairs (0,5), (1,8), (2,11), (12851, 38558) are the solution for the given pair of equation
Hence, the given equation had infinitely many solutions.
