I need help with a very general question. I was asked to find the instantaneous velocity of a position time graph at .5 seconds. i know to do this i need to create a line that is the tangent to that point. Here lie the problem... how on earth do i make that line, and how do i measure the slope?(adsbygoogle = window.adsbygoogle || []).push({});

i think (y2-y1/x2-x1)for finding the slope of the tangent line? but i have no idea where that line should begin or end.

Thanks
