Question

Ms.Koehler is planting A treat to help save the environment. She decided to keep track of the height of the tree over the years. After the first year Ms. Koehler measured the tree to be 8 feet tall. She took note that this was an increase of 3 feet from the previous year. Assuming the tree will continue to grow at this rate I answer the following questions.

Write an equation representing the height of Ms. Koehler’s three overtime, where y represents the height of the tree and x is the number of years since being planted

Answer:

y = 3x +5

Explanation:

We are told the height increase is 3 ft in 1 year. That is the slope of the linear function representing height.

We are told that in year 1 the height was 8 ft, and that it was 3 ft less in the previous year. That is, it was 5 ft high in year 0. So, the y-intercept of the function is 5.

The slope-intercept equation is ...

y = mx + b . . . . for slope m and y-intercept b

y = 3x + 5
