4. The FRAME Routine Key Topic Main idea is about… So What? (What’s important to understand about this?) Essential details Main idea Essential details Main idea Slope-Intercept Form A linear equation written in the form y = mx+b. Slope y - interceptVariables Change in y’s over change in x’s. Rise over run. Can find it by: y2 – y1 =m x2 – x1 What is it? Where in the equation Coordinate points Represented by “m” in the equation y = mx+b. Represented by “b” in the equation y = mx + b. Represented by “x” and “y” in the equation y = mx + b. Slope is constant only in a linear equation Always one constant number in a linear equation The coordinate points will change These numbers will vary. Can find only one if given the other. Where the graph crosses the y-axis. Find y where x = 0 Is it constant This will help make graphing and solving linear equations easier. Linear equations are used to model things over time such as distance over time or cost over time (speed and inflation).
