Question

Solve for y, m and b. Add 2 choices that behave similarly to your part 1 program, but have the user solve for m and b instead. These choices should also randomly generate problems, and print if the user answers correctly. Your main program should display a menu asking which type of question to ask: Select 1 to Solve for Y, 2 to Solve for M, 3 to Solve for B and 4 to quit. When the user selects the question type, one question should be asked, then the user should return to the menu. This should repeat until the user selects quit, then the program should exit. Use one or more methods and loops to produce this behavior.

Here is what i have so far (i've bolded where i need help), and i cannot figure out what to do from here. I have a general idea, but no clue how to execute.
