        for i in range(2, len(coordinates)):
            x1 = coordinates[0][0]
            y1 = coordinates[0][1]

            x2 = coordinates[1][0]
            y2 = coordinates[1][1]

            x3 = coordinates[i][0]
            y3 = coordinates[i][1]

            if (y2 - y1) * (x3 - x1) != (y3 - y1) * (x2 - x1):
                return False
