Spread the loveIntroduction Slope and intercepts of a line are fundamental concepts in mathematics, especially in algebra, calculus, and geometry. Calculating the slope (m) tells us how steep the line ...

If you think about how we look at factors and roots later on, introducing standard form earlier could make a lot of sense. For the equation 3 x + 4 y = 24, we can imagine x = 0 and see that y must ...
