The amount a tree grows in one month is directly proportional to the amount of water it is given When the tree is given 23 gallons of water, it grows 4 cm that month. What is the constant of proportionality for this variation? Round your answer to the nearest thousandth.

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
