It would be 3 because the numbers with the variables are the same which is 2. Then if we would substitute the variables with the coridanates the equation would be 2x4 + 2x-2 = 12. Then if you solve the equation using pemdas you would get 4. 4 would not equal 12 which means the equation is not true. So 3 cannot use this set of numbers but the rest can.
