Every straight line you’ve ever seen hides this simple equation: y = mx b. In this video, we’ll break down what each part means — m (the slope) and b (the y-intercept) — and show how changing them transforms your line on the graph. Perfect for Algebra 1, Pre-Algebra, or SAT Math prep. You’ll finally see how this formula builds every line you’ve ever graphed! 👉 Grab my Linear Equations Practice Sheet here: https://www.teacherspayteachers.com/Product/Algebra-1-Chapter-2-Bundle-Linear-Equations-Fu
