Answer:
Undefined.
Explanation:
We want to find the slope of the graph of the equation:
At the point (9, 0).
In other words, we want to evaluate dy/dx when x = 9 and y = 0.
Find dy/dx. We can take the derivative of both sides with respect to x:
Then the slope of the graph at the point (9, 0) will be:
In conclusion, the slope of the graph at the point (9, 0) is undefined.
