For 90 ! ! i'm stuck on this!
3. 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.
(a) what is the equation of the line, written in slope-intercept form? show how you determined the equation.
(b) based on the linear model, predict how long anika worked on the setup crew on the day the fair arrived at the fairgrounds, day 0. approximately how much did her setup time decrease per day?
