The derivative of a function at a point gives the slope of the line tangent to the function's graph at that point. 

Therefore,   gives the slope of the tangent line to the graph of  where   , which is the point . 

We know this line passes through  , and we are also given that it passes through . This should be enough to find the slope of that line. 

 

 

 

In conclusion, 

A
