The domain of the graph is all real numbers because the value doesn’t have an end point.
In simplest form (smallest possible answer) the ratio is equal to 2:3. But it is also equal to 4:6.
Tanθ = 8.9352
θ = tan⁻¹ (8.9352)

The slope of the line is the velocity, or rate of change, of y with respect to x. In other terms, the slope tells you how much y will change for every change in x by one unit. For example if the slope, which is velocity, is 2. y will increase by two units every time x increases by one unit. Your graph is not pictured nor explained, so I cannot give you the specific context beyond the principle that the slope of a line is a constant velocity or rate of change.
