Answer:
The range is all real numbers.
Step-by-step explanation:
Range is simply all the y-values you could have when you substitute any given x-value.
Domain refers to all x-values that can be substituted into a function.
In the case of linear functions with a gradient, which are line equations, both the the domain and range are always "all real numbers" because any x-value can be substituted into the function and any y-value can be generated.
