  1. 4.4 Find Slope and Rate of Change

  2. change in y rise = change in x run Slope • slope—ratio of the rise to the run of a line m = variable that stands for slope Negative Fractions Why are these fractions equal?

  3. Find Slope • First way to find slope is to look at the graph **Does not matter which direction you start with to count—get the same answer

  4. b) a) Ex 1: Find the slope Horizontal line—slope of 0

  5. d) c) Ex 1: Find the slope Vertical line—slope of undefined

  6. Calculating Slope

  7. Example 1

  8. Example 2

  9. Determine rate of change • A car travels 50 miles in 2 hours and 175 miles in 5 hours. Determine the cars rate of change.
