plot

Plot $f (x) = 2 x + 4$ $f(x) = 2x + 4$ which is a linear plot with $slope = 2$ $"slope" = 2$ , and intersecting the y axis at $(0, 4)$ $(0,4)$

graph{2x +4 [-8.52, 16.79, -0.28, 12.38]}

Then plot $g (x) = 8$ $g(x) = 8$ , an horizontal line at $y = 8$ $y = 8$ .
graph{8*(x/x) [-4.59, 23.88, -1.05, 13.19]}

Plot both on the same plane and highlight the left-hand side intersection as it's a " $<$ $<$ " inequality.
