2. Specification - Given the attached code, import the module and use the functions to ask the user for two equations of a lines. Use the module function to decipher the functions and output the intersection point. Currenty only allow basic operations (no parenthesis)...but could support more options in the future. Sample Output: Enter Equation 1: +3 Not valid, must have equal sign Enter Equation 1: y = x+3 Enter Equation 2: y/3 - 100x+(3-10) Not valid, special characters (0) Enter Equation 2: y/3 = -10z+(3-10) Only x and y allowed Enter Equation 2: y = -x Intercept at (-.6666,0) 2.
