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.

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
