In a function like yours, which is a straight line, there are no restrictions on the domain. Since there is no x in the denominator, no x in a root, or any other thing that could cause a non-real root, x can be every value from negative infinity to positive infinity.

Hint: All polynomials have a domain of R, or $$(-\infty,\infty)$$ A first degree curve is a polynomial.
