The domain and range of the equation y = 2x+8 are both [-infinity,+infinity].
The answer depends on the domain for x. For example, if the domain is x = 7, then the range is 55. If the domain is all Real numbers, then the range is y >= 6.
The domain is related to the range depending on the equation or equations given. Without this context, the domain for a Cartegian plane (2 dimensions) is simply R, or all real numbers. With a linear equation (absolute value/ dependent variation) a more useful and specific answer can be given.
If the domain is the set of real numbers, so is the range.
Domain is the spectrum of values on the x-axis. Domain will be which x-values can be plugged into that equation and give an answer. Range is the same thing, but y-values. On the graph it will be the y-values that are included in the graph.
