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.

Respuesta :

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

[tex]y=mx+b[/tex]

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:

[tex]4(12)=48[/tex]

48 is the starting height of tree in inches

Next, the equation is:

[tex]y=3x+48[/tex]
