This link has the exact graph that relates to my question.

I have tried answering the question however, the formula that is provided in my book for instantaneous velocity is change of V/change of t as the limit of t approaches 0. The problem is that when they are asking me the instantaneous speed of the first point like A , what is the second point that I need to use to input the change of velocity and t on the formula?

I really appreciate the help. Thank you.

You have to understand that \frac{dv}{dt} is the gradient of the graph. If I ask you what is the gradient of the graph at the point A. Can you find the instantaneous velocity?

I hope it helped! :)
