Question 241140
Hello, 
Here's how we check this out. Let's check the first one (-4,-3) Plug it in:
5(-4)-3(-3)>15 Do the calculations and it gives us: 
-20+9>14 Combine like terms
-11>14  This is false
So let's try the second (2,2)
5(2)-3(2)>15  This works out to:
10-6>15 or 
4>15  This is also false. There you go.
