Answer
Refer to the image below for the graph.
Work Step by Step
Divide both sides of the equation by $9$ to obtain:
$\dfrac{9y}{9}=\dfrac{x^2}{9}
\\y = \dfrac{x^2}{9}$
To graph the given equation, perform the following steps:
(1) Create a table of values by assigning values to $x$ then solving for the corresponding value of $y$ for each one.
(Refer to the attached image below)
(2) Plot each ordered pair from the table of values then connect the points using a smooth curve to form a parabola.
