Question

Which ordered pair is a solution to the equation?

y = 1/2x-4
O (12,2)
O (18,12)
O (-3,5)
O There are no correct solutions shown.

Is there a typo?

Answer 1

There is no typo in the equation. The ordered pair that is a solution to the equation is **(12, 2)**. To check this, we can substitute the values of x and y in the equation and see if it is true.

y = 1/2x - 4

2 = 1/2(12) - 4

2 = 6 - 4

2 = 2

This is a true statement, so (12, 2) is a solution to the equation.

The other ordered pairs are not solutions because they do not satisfy the equation. For example, if we try (18, 12), we get:

y = 1/2x - 4

12 = 1/2(18) - 4

12 = 9 - 4

12 ≠ 5

This is a false statement, so (18, 12) is not a solution to the equation.

Similarly, we can check that (-3, 5) and "There are no correct solutions shown" are also not solutions to the equation.
