Answer:
yes
Step-by-step explanation:
To figure out if a point works with it's equation, you should replace the x and y with the point you got
-8 > 3(-5)+6
-8 > -15 +6
-8 > -9
Since -8 is bigger than -9, point (-5,-8) is true to the equation.
and as seen in the graph I have attached, the point does infact reside in the shaded in area. If you haven't learned how to graph this type of equation, you may disregard the graph :)
If you have any questions at all, don't be afraid to ask :)
