Linear Equation

posted by .

I posted a question below but forgot to put in the equation! So sorry. The problem states: Find 2 numbers that satisfy the equation then graph it.
The equation is 2y+2=0
I think one of the numbers is -1, but what could the other be or am I doing the problem incorrectly? Thanks so much for any help.

I don't believe there is another number.
