. A line can also be modeled by its slope m and its Y-intercept h i.e. y = mx + h). Write a structure that models lines with these two components. Write a function that takes two lines and gives their intersection point. In case of being parallel lines, the function returns the point (NAN, NAN). In case of being overlapping lines, the function returns the point (INFINITY, INFINITY). Test your function in the main program
