Andres graphed the equation x=y^2 on a coordinate plane...
1 answer:
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 =
⇒⇒⇒ 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)
