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 (y-intercept). approximately how much did his delivery time decrease per day (slope)? answer in complete sentences

b = 10

so point slope form would be

     Y – 6 = -1/3 (x - 12)

Slope Intercept form:

y = mx + b

m is the slope so use the formula for slope to find the slope

formula for slope: m=(y2-y1)/ (x2-x1)

m = (6-3)/(12-21) = -1/3

so the slope intercept form would be:

y - 6 = -1/3 (x-12)

(b) based on the line,I predict it initially took scott 30 minutes to deliver his packages 

for part two of the question you have to find the unit rate, or just look at difference between each day

Scott`s delivery time decreased pproxiametely 2 minutes per day

Can i please get brainliest? I worked really hard on this

can you rephrase the question ? it is unclear : -)
