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).

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
