Initially, I had no idea what I was looking at in the first graph. At some point down the road, whether it was by divine intervention or some other superficial method, I began to more easily see and understand the relation between the point and slope. The biggest problem for me was developing a working graph. I don't exactly excel at open-ended math problems; the close-ended problems are hard enough. I wouldn't necessarily I overcame my difficulty, I just plugged and chugged until I got the desired answer. The second graph was essentially a more generalized version of the first. Variables replaced exact points. The third graph was very easy to create after the first two; just a few values and variables were changed from the original formula(s). As the secant lines approach each other, they come closer and closer to forming a tangent line.
