Andres graphed the equation x=y^2 on a coordinate plane...
Accepted Solution
A:
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 = [tex] \sqrt{-1} [/tex] ⇒⇒⇒ which is unacceptable i.e. x ≠ 1 ∴ the ordered pair does not satisfy equation (2) ⇒⇒⇒ Jody's equation
