Question

Andres graphed the equation x=y^2 on a coordinate plane...

Answer 1

Andres graphed equation ⇒⇒⇒ x = y²   (1)
Jody graphed equation    ⇒⇒⇒  y = x²   (2)

Checking the ordered pair (1,-1):
--------------------------------------------
substituting with y = -1 in equation (1)
So, x = (-1)² = 1
∴ the ordered pair satisfy equation (1) ⇒⇒⇒ Andres 's equation

substituting with y = -1 in equation (2)
So ,   x² = -1
       ∴ x = $\sqrt{-1}$  ⇒⇒⇒ which is unacceptable
     i.e. x ≠ 1
∴ the ordered pair does not satisfy equation (2) ⇒⇒⇒ Jody's equation


So, The correct statement will be option (A)
