1. scott works as a delivery person for a shipping company. the graph shows a linear model for his delivery times on different days.

(picture of graph included )

(a) identify two points on the line and write the coordinate pairs below.

(b) use your two points to find the slope, and make sure to show your work.

(c) use your slope from part b and find the equation of the line in point-slope form. show your work and work through the steps to transform the equation from point-slope form into slope-intercept form.

(d) based on the equation you found in part c, predict how long it initially took scott to deliver his packages. approximately how much did his delivery time decrease per day?
