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 :)
To find when their costs will be same, we can set them equal to each other.
While writing the equation, we need to take into account that one plan has a base payment of 75 no matter how much Justin drove. And there are changeable values which are effected by the x, the miles driven by Justin.
So the equation is
When we subtract
from both sides: 
Divide both sides by
: 
He needs to drive 750 miles to make 2 plans' cost equal.
