A survey was distributed to a group of people asking them how many times they had ordered takeout in the past week. They were also asked how much money they saved that week. The scatter plot displays the relationship between the data collected.  the trend line goes through the points (1,230) and (3,190). What is the equation of the trend line. The equation should be in slope form.  interpret the slope and y intercept in this context.  predict the amount of money a person save when they order takeout 9 times.

Is the slope of the line shown 0?
