Answer:
See Graph Below
Domain: All Real Numbers
Range: All Real Numbers
Explanation:
For the graph, simply make your first point at 7 (the y-intercept) and then move 4 y's up for every x.
For the Domain: The answer would be all real numbers because you can plug any real number into x and the equation would be solvable.
For the Range: The answer would be all real numbers because there is no y that is impossible to reach via x.
