The Graph That’s Everywhere: y = mx + b!

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!
