Draw the cause-and-effect graph

Suppose a mathematician’s calculator has a function that computes the slope and intercept of a line.The requirement in the definition document reads:“The calculator shall accept as input an equation of the form and print out the slope and intercept.”The system implementation of this requirement is the function LINE whose syntax is LINE(A,B,C), where A and B are the coefficients of x and y, and C is the constant in the equation.The result is a printout of D and E, where D is the slope and E the intercept.

Write this requirement as a set of causes and effects, and draw the corresponding cause-and-effect graph.

Solution:
