1) The Magnolia trees purchased for planting at the school are 3 feet tall. Research shows that these types of trees grow at an average rate of 3/4 foot per year.

a) Write an equation in Slope-Intercept form to represent the growth of the trees over time. Let x represent the number of years and let y represent the height (in ft.) of the tree.

Y=3/4x+3


b) What does the y-intercept represent in your equation

Stands for feet Y=3 3


c) Determine the height of the tree in 3 years.


Y=3/4×3+3=9/4+3=21/4=5.25 feet


Could the equation 3x - 4y = - 12 be used to represent the same information in question #1? Explain your reasoning

a) What does the 3 and the 4 in this equation tell us?

b) Using this equation can you tell me how tall the tree will be in 24 years?


c) Using the equation find the x-intercept. What does this mean in this problem?​
