The slope equation.

Let's say you have a line with two points (x1, y1) and (x2, y2). Your task is to find the slope m of the line whose points are (2, 3), (6, 7). The formula to calculate the slope of theline is:

m = (y2 - y1)/(x2 - x1)

You have to store your answer in the variable m

class TestEquationSolver(unittest.TestCase):
    def test_slope(self):
        self.assertEqual(m, (7 - 3)/(6 - 2))
