Which of the following ordered pairs is a solution of x + 1/2y = 1?

(-2,6)

for example  

x+1/2y=1  

the ordered pair i will use is the first one. (-2, 6)  

so  

(-2) + 1/2(6)=1  

from there it is a simple add/subtract and multiply/divide math problem.  

1/2(6)=3  

so  

(-2) + 3 = 1  

yes this ordered pair works for the solution meaning it is the answer.

understand that i don't know the answers

will someone answer his question
