Suppa;e 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 Ax + By + C = 0 and print out the slope and intercept."The system implementation of this requirement is the function LINE whose syntax is LINE(A,B,C), whe re A and Bare the coefficients ofx andy, and C is the constant in the equation.The result is a printout of D and E, where Dis the slope and Ethe intercept. Write this requirement as a set of causes and effects, and draw the corresponding cause-and-effect graph.
