The domain is whatever you choose it to be. It can be all natural numbers, or all even integers, all numbers of the form k+1/3 where k is an integer, all real numbers, whatever! When you have selected a domain the function will determine a range.
The domain of y = -4x is all real numbers.
(2, 7)
Y = x squared -4x plus 3 is an equation of a function. It is neither called a domain nor a range.
Parallel, the slope of the second equation is 4
4x-5y = 13 -5y = -4x+13 y = 4/5x-13/5 Slope = 4/5 or 0.8
4x - y = 1 3x + y = 13 Add the equations: 7x = 14 so that x = 2 and then, by the first equations, 4*2 - y= 1 so that y = 7
y equals 4x+1 is a parallel line to y equals 4x.
This is the equation of a line with slope -4 and y intercept at 0. The domain is all real numbers as is the range.
4x = y : or it can be written in the reverse order, y = 4x.

8 + y = 4x8 + y - 4x = 4x - 4x 8 + y - 4x = 0 8 - 4x + y = 0
