Tangent Lines

Ok someone asked about this and I couldn't find the blog again... These are what we consider "gimme" questions. They usually don't have complicated derivatives, etc. In an non-implicit problem. You take the derivative of the equation given and then plug in the x-value given to get the slope. Then you plug the slope and x-value into point slope. You will need the y-value to finish the point-slope equation. If it is not given you find it by plugging the x-value into the ORIGINAL equation and solving for y. See several of the problems we have done in earlier APS. We had one in the diagnostic test I believe.
