100 POINTS PLEASE HELP D:

Anika is on the crew to set up rides for the state fair. The crew does most of the setup on the day that the fair arrives at the fairground and then continues to work on finishing the setup for about a week to have the rides ready to go in time for the opening of the fair. The scatter plot shows Anika's setup time on different days and the linear model for the data.
Y = setup time ( HOURS )
X = time ( DAYS )
(a) What is the equation of the line, written in slope-intercept form? Show how you determined the equation.


(b) Anika arrived on Day 0. Based on the linear model you created in Part A, predict how long Anika worked on Day 0.

(c) Approximately how much did her setup time decrease per day?

Answer:

Step-by-step explanation:

See the attachment for derivation of the equation.

y = -(6/7)x + 20 6/7

The y-intercept of the equation is 20 6/7, which means there is 20 6/7 hours of setup time required.  When Anna arrives, she has not yet done any setup, so she would not have done any work yet.

In any event, the graph does not tell us how much time Anna really worked.  Did Anna spend 6 or 9 hours on the setup?  We don't know.
