julia has made 9 posts while trying out a new social media platform. starting now, she plans to make 1 post daily. write an equation that shows how the total number of posts, y, depends on the number of elapsed days, x. y =

Answer

Explanation:

Step1: Analyze the initial value

Julia has already made 9 posts. So when (x = 0) (at the start of counting days), (y=9). This is the y - intercept (b) of the linear equation (y=mx + b).

Step2: Analyze the rate of change

She makes 1 post per day. The rate of change (slope (m)) is 1. Using the slope - intercept form (y=mx + b), substituting (m = 1) and (b=9)

Answer:

(y=x + 9)
