Question

Which ordered pair will be solution for the function y = 12 - x ?

(4, 9)
(6, 6)
(2, 14)
(7, 4)

Answer 1

(6,6)

Explanation:

to solve these equations, all you have to do is plug in the x and y values. the ordered pair will be a solution if the expression - after being solved - is true. when you plug 6 and 6 in, you get 6=12-6. Once simplified, it is 6=6. This is true and will always be true.
