# Tangent Line Slope Exploration

Type in the coordinates of a point on the graph. The tangent line will move to that point and the slope of the tangent will be plotted as a point (x, slope). Note the slope of the tangent line at that point. Guess the formula for the slope function by changing s(x). Does your guess pass through all the plots of the slopes? Change f(x) to test your skills.
