Which ordered pair is a solution of y=x+12?

9,21

Step-by-step explanation:

Check each pair separately

(-12, 24) - if x=-12, then y = 24

let us check with substituting the value of x in the equation and finding y

y = - 12 + 12 = 0

if x = - 12, y = 0, which does not correspond to your pair

Check the next ones the same way

(12,24)

x = 12

y = 12 + 12 = 24

(12,24) - a solution

(0,-12)

x = 0

y = 0 + 12 = 12, not - 12

(-12,0)

x = - 12

y = - 12 + 12 = 0

true

(-12,0) - a solution

So, we have to pairs that are the solutions for the given equation

(12,24) and (-12,0)
