We are given the following equation:

To determine if the point (1, 3) is a solution to this equation we will replace the given values since the point (1, 3) means that when x = 1, y = 3. Replacing in the equation:

Solving the operation we should get the same value on both sides of the equation:

Since both sides are different this means that the point (1, 3) is not a solution to the equation.
