CAP COUNCIL a. For linear functions, the slope of any secant line always equals the slope of any tangent line b. The slope of the secant line passing through the points P and Q is less than the slope of the tangent li c. Consider the graph of the parabola f(x) = x. For x>0 and h> 0 the secant line thround CAP COUNCIL a. For linear functions, the slope of any secant line always equals the slope of any tangent line b.
