Estimate the rate of change from a graph. MCC9‐12.F.IF.7 Graph functions expressed symbolically and show key features of the graph, by hand in simple cases and using technology for more complicated cases. Learning Target * Find the rate of change and average rate of change of a function over a given interval.
- 5. *Big Ideas The slope of a line is the measure of its steepness. The formula for calculating the slope of a line is: 2 - -4 y2 x2 y1 x1 9-0 How much did “y” change or how far apart are the two numbers on a number line ? How much did “x” change or how far apart are the two numbers on a number line? 6 9 rise run (x,y) (9,2) (x,y) (0,-4)
