Q. apsb.info bookmarks\newlineThis graph shows how a sapling's height depends on its age.\newlineHeight of a sapling\newlineWhat is the rate of change?\newlineWrite your answer as a decimal or integer.\newline□ \square inches per year
  1. Look at the graph: Look at the graph and find two points to calculate the rate of change. Let's say the points are (1,3)(1, 3) and (4,15)(4, 15).
  2. Use the formula: Use the formula for rate of change which is (change in height)/(change in time)(\text{change in height})/(\text{change in time}). So, it's (15−3)/(4−1)(15 - 3)/(4 - 1).
  3. Do the math: Do the math: (15−3)=12(15 - 3) = 12 and (4−1)=3(4 - 1) = 3.
  4. Divide to get rate: Now divide 1212 by 33 to get the rate of change. So, 12/3=412/3 = 4.
