Quizplus · Accepted Answer

To determine if the ordered pair $(9, -1)$ lies on the graph of the equation $y = \sqrt{x} - 4$, substitute $x = 9$ into the equation and see if $y$ equals $-1$. Substituting $x = 9$ gives $y = \sqrt{9} - 4 = 3 - 4 = -1$, which matches the $y$-value of the ordered pair. Therefore, the ordered pair $(9, -1)$ does lie on the graph of the given equation.

Determine Whether the Indicated Ordered Pair Lies on the Graph y=x−4,(9,−1)y = \sqrt { x } - 4 , ( 9 , - 1 )y=x​−4,(9,−1)
