a.
Answer to Problem 13E
The point
Explanation of Solution
Given:
The equation
Concept Used:
For a point to be on the graph of its equation, the point has to satisfy the given equation.
That is when substitute the value of
Calculation:
For the givenequation
Substituting the point into the equation.
i.e.,
Left hand side
Right hand side is
Since, left hand side isnot equal to right hand side.
Therefore, the point
