Since all of the points are on the graph and go on forever it would be:

Domain: {all real numbers}

Range: {all real numbers] :) You are correct on two too. The graph of the line extends all the way left and right (so the domain is all reals) and it extends all the way up and down (so the range is all reals).

Be careful on the third problem. One of the answers is "all reals" but the other answer is not!
