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.
