# Graph x^2+y^2<9 Solve for .
Subtract from both sides of the inequality.
Take the square root of both sides of the inequality to eliminate the exponent on the left side.
Simplify the right side of the equation.
Rewrite as .
Since both terms are perfect squares, factor using the difference of squares formula, where and .
The complete solution is the result of both the positive and negative portions of the solution.
First, use the positive value of the to find the first solution.
Next, use the negative value of the to find the second solution. Since this is an inequality, flip the direction of the inequality sign on the portion of the solution.
The complete solution is the result of both the positive and negative portions of the solution.
and
Find the intersection.
The equation is not linear, so a constant slope does not exist.
Not Linear
Graph a dashed line, then shade the area below the boundary line since is less than .
