$x^{2} > y$ , $(2, 9)$

Step 1

Insert the values of $x = 2$ and $y = 9$ into the equation to find if the ordered pair is a solution.

${(2)}^{2} > 9$

Step 2

Raise $2$ to the power of $2$ .

$4 > 9$

Step 3

The inequality is never true.

No solution

Step 4

Identify the leading coefficient.

Step 4.1

The leading term in a polynomial is the term with the highest degree.

$- 5$

Step 4.2

The leading coefficient in a polynomial is the coefficient of the leading term.

$- 5$

Step 5

Since there are no real x-intercepts and the leading coefficient is negative, the parabola opens down and $- 5$ is always less than $0$ .

No solution

Step 6

Since the equation is not true when the values are used, the ordered pair is not a solution.

The ordered pair is not a solution to the equation.
