(-oo,oo)(,) for both domain and range

Explanation:

Since the equation is a line, all values of xx produce a real value of yy.

As xx approaches oo, yy approaches oo.

As xx approaches -oo, yy approaches -oo.

Since the equation does not have fractions or radicals, both the domain and range take on all real values.
