(a)

\

The equation is $\"\"$ and the point is $\"\"$ .

\

To check the solution, substitute the values of $\"\"$ in the original equation.

\

$\"\"$

\

$\"\"$

$\"\"$

\

$\"\"$

\

$\"\"$ .

\

\

The above statement is false.So the point $\"\"$ is not a solution of the equation $\"\"$ .

\

The point $\"\"$ is does not lie on the graph of $\"\"$ . $\"\"$

(b)

\

The equation is $\"\"$ and the point is $\"\"$ .

\

To check the solution, substitute the values of $\"\"$ in the equation $\"\"$ .

\

$\"\"$ .

\

\

The above statement is true.So the point $\"\"$ is a solution of $\"\"$ .

\

The point $\"\"$ is lies on the graph of $\"\"$ . $\"\"$

\

(a) The point $\"\"$ is does not lie on the graph of $\"\"$ .
