           +----EDU.emporia.mathbeans.SecantLine

Generates a MathFunction corresponding to a secant line between two points of the specified curve.

f: The function to which the line is secant.
slope: The slope of the line
xOne: The x-coordinate of the first point on the curve used to determine the line
xTwo: The x-coordinate of the second point on the curve used to determine the line
yOne: The y-coordinate of the first point on the curve used to determine the line
yTwo: The y-coordinate of the second point on the curve used to determine the line

functionValue(double): Gives the y-coordinate of the point on the secant line with the indicated x-coordinate.
getF(): Gets the function used to determine the secant line.
getSlope(): Gets the value of the slope of the secant line
getXOne(): Sets the x-coordinate of the first point used to construct the secant line
getXTwo(): Gets the x-coordinate of the second point used to construct the secant line
setF(MathFunction): Sets the function used to determine the secant line.
setXOne(double): Sets the x-coordinate of the first point used to construct the secant line
setXTwo(double): Sets the x-coordinate of the second point used to construct the secant line
updateSlope(): Updates the value of the slope to reflect any changes made in the points or in the definition of f.
