Answer: FALSE.

Step-by-step explanation:

Given the system of inequalities:

\left \{ {{y>-2x-2} \atop {y< 3}} \right.

We can know if the point (-2,3) is a solution to the following system with the graph of the system of inequalities.

 By definition the solution is the intersection region of all the solutions of the system of inequalities.

Knowing this and analizing the graph attached, we can notice that the point (-2,3) is not included in the intersection region (Remember that with symbols "<" and ">" the lines are dashed and any point that lines of these lines is not included in the intersection region).

Therefore, it is not a solution to the system.

PLEASE HELP!
Kitty [74]
You can reword the two equations as:

-5x-y=15 (Divide original value by 3)
-2x+6y=6

Then use elimination to find x:

-30x-6y=90 (Multiply by 6 to get y values to be same to cancel out)
-2x+6y=6

You're left with:

-32x=96. Which can then be solved to find x which is -3.

Then plug back in 

-2x+6y=6

Now to: -2(-3)+6y=6.

Which reduces to 6+6y=6. So y=0.



To graph them, just reword the equations (yes once again) so that y is in front.

y=-5x-15 and y=(1/3)x+1
