You could draw a graph or rewrite the inequality in terms of y as a variable for x, but fundamentally y>=3x+6 is a solution form.

Explanation:

As a graph
graph{y>=3x+6 [-10, 10, -5, 5]}

Rewritten, solving for x in terms of y
color(white)("XXXX")y >= 3x+6

color(white)("XXXX")y-6 >= 3x

color(white)("XXXX")y/3-2 <= x
or
color(white)("XXXX")x<= y/3-2
