The following solutions to the given system of inequalities shown above would be option c : (-3, -5) option d : (0, 4)  option e. (4, 4)  and option f. <span>(2, -1) 
So how did I know the answer. To check this, you just have to substitute the values.
For example let us take option c (-3, -5)
y </span><span><  3x + 5
-5 </span><span><  3(-3) + 5
-5 </span><span><  -9 + 5
-5 </span><span><  -4 <<You see that -4 is greater than -5 which makes this inequality correct. This is the same process as with the other correct options.
Hope that this answer helps.</span>
