Question

Hello could you please help me with this question? 7. Write a linear equation in slope-intercept form to model a tree 4 feet that grows 3 inches per year.

Answer 1

A linear equation in slope-intercept form is given by:

$y=mx+b$

Where:

b = starting height of tree = 4 feet = 48 inches

m = inches per year = 3 inches

x = the number of years of new growth

First, We convert the 4 feet in height to inches, to work in the same units. We know that 1 foot = 12 inches, therefore:

$4(12)=48$

48 is the starting height of tree in inches

Next, the equation is:

$y=3x+48$
