Question

A giant bamboo plant grew an average of 18 centimeters per year.The botanist started measuring the plant when it was 5 centimeters tall. If "Y" represents the number of years the botanist has measured the plant,what expression represents its height?
Solve,and show each step.

Answer 1

H=height
y=number of years.

we have the next expresion:
h(y)=my+b  

m=the slope of the line, in this case, the slope is equal to "18"; (18 cm/ year).
b=the initial heigth, in this case, the initial heigth is equal to "5" (5 cm).

Therefore, our  expression will be:
h(y)=18y +5

answer: h(y)=18y+5
