plotplot

Explanation:

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

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

Then plot g(x) = 8, an horizontal line at 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.
