Bamboo trees grow at a constant rate. You measure your tree 8 days (x) after you purchased it and it was 25 centimeters tall (y). You measure again 15 days (x) after you purchased it and it is now 39 centimeters tall (y). What is the growth rate of the tree? How tall was it when you brought it home (on day 0)?Create an equation is slope-intercept form that gives me the rate (m) and the initial height (b).
