Notes: P.2 Linear models and rates of change
Linear Equations Formulas Can you… • Standard Form • Point-slope Form • Slope-intercept form Graph? Find intercepts? Find the slope? Change it into other forms?
Slope • Slope, , is the rate of change for the linear equation • When , you get a horizontal line • When is , you get a vertical line
Parallel and Perpendicular Lines Two distinct nonvertical lines are parallel if and only if their slopes are equal—that is, if and only if . Two nonvertical lines are perpendicular if and only if their slopes are negative reciprocals of each other—that is, if and only if
Technology Pitfall When graphing on calculator, aspect ratio of screen is not square. You can switch to square setting (Zoom 5) to make it square :-)
