The domain is defined as all the possible x values. The graph extends to the left and to the right without bounds so the domain is All Real Values of x.
It can also be written as (-∞, ∞) This is called interval notation.

Note that the minimum value of f(x) is -4 so the range is [-4, ∞). (All real values of y equal to or greater than -4)

The graph of y = -5x + 1

y = -5x + 1

[y = mx + b "m" is the slope, "b" is the y-intercept (the y value when x = 0)]

So your slope is -5, and your y-intercept is 1 or (0,1)

$Slope = \frac{rise}{run}$

Rise is the number of units you go up(+) or down(-).

Run is the number of units you go to the right.

Since your slope is -5 or $\frac{-5}{1}$ , you go down 5 units, and to the right 1 unit.
