Do you have any choices that go with this???

anonymous · Answer

(1, -5) 

(1, 5) 

(5, 1) 

(-1, 5)

yanasidlinskiy · Answer

Plug them in and see which one works.

anonymous · Answer

how?

yanasidlinskiy · Answer

Try them out.... Plug one # for the first x and plug in the other # for the second x...what did you get???

For example, if you chose to test (-1,5), you'd substitute x=-1 and y=5 into both of the given inequalities and determine whether or not both are true.  If both are true, then (-1,5) is a solution; if only one, or neither, is/are true, then (-1,5) is NOT a solution.

Alternatively, you could graph both inequalities yourself, and then determine whether (-1,5) lies in the doubly-shaded area.  If you need help with this graphing, let us know.
