The height of a tree grows by four inches every year, with A1 = 22 inches. Select the explicit rule which represents this situation.

4x+22

Step-by-step explanation: From My understanding This is how my teacher taught me how to do it in 7th grade Pre-Ap math class Hope this helps:)

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
