Question 1058462: 1. Scott works as a delivery person for a shipping company. The graph shows a linear model for his delivery times on different days.

(a) What is the equation of the line, first written in point-slope form and then written in slope-intercept form? Show how you determined the equation.
(b) Based on the linear model, predict how long it initially took Scott to deliver his packages. Approximately how much did his delivery time decrease per day?
I don't know how to add the photo of the graph!The (x,y) coordinates are (3,21)(6,12)

If this is for just a line with those two given points, then use them to find slope, and pick either point and use the point-slope equation form. Simplify or transform into slope-intercept form.

--------simplify and put into format y=mx+b.
