This concept covers computing the tangent line to a polynomial curve at a specified point by combining the derivative (via the power rule and sum rule) with the point-slope form of a line: the derivative function gives the slope as a function of x, which must then be evaluated at the specific x-coordinate of the point of tangency to obtain a numerical slope, which is then paired with the given point in the point-slope equation. This belongs to single-variable calculus, at the interface between differentiation rules for polynomials and the geometric interpretation of the derivative as the slope of a tangent line, itself an application of coordinate/analytic geometry (equations of lines).
