8) The slope of a line containing the points (x1, y1) and (x2,y2) is given by the formula m =(y2-y1)/(x2-x1) a) write a segment of Python code that will calculate the slope of the line containing the points (2, 3) and (3, 6) b) Rewrite your solution to a function. The name of the function is 'slope' t takes the x- and y-coordinates of the two points as parameters. It returns the slope. It does not print any information on the screen and does not interact with the person who is running the program
