Write a Python Function based on the question.

Problem 4: Visualizing solutions to ODEs Grading criterion: correctness of code and readability of plot. 4a. Use Sage to solve the ODE y' (1 -2)ev In b. Plot the slope field corresponding to the ODE in 4a along with three different solutions (coming from different initial conditions).
