Secant and Tangent Lines Quiz

• A secant line to a graph is any line connecting a point P and another point Q on the graph.
• The tangent line to a graph at point P is the limiting position of all secant lines PQ as Q approaches P.
• The tangent line may not exist if the function is not continuous at the point P or if the function has a sharp corner/cusp at P.
• The slope of a line passing through two distinct points can be found using the slope formula.
• The point-slope form can be used to find the equation of a line passing through a known point with a known slope.
• To find the slope of the tangent line, compute the limit of the difference quotient as x approaches x0.
• The slope of the tangent line can also be found by taking the limit of the difference quotient of the function at x0.
• To find the equation of the tangent line, substitute the slope and coordinates of the known point into the point-slope form.
• The equation of the tangent line gives a linear approximation of the graph near the point P.
• The tangent line is the best linear approximation of the graph near the point P.
