Domain ${x|x " is " RR}$
Range ${y|y " is " RR}$

$y=2x-7$ is the equation of a line with slope $m=2$ , the domain and range of any line with $m!=0$ and $m!=O/$ is all real numbers:

Domain ${x|x " is " RR}$
Range ${y|y " is " RR}$

How do you find the domain and range of y = 2x - 7y=2x−7y = 2x - 7?
