100 points 1. Peter works as a delivery person for a bike shipping company. The graph shows a linear model for his delivery times on different days.
Peter’s Deliveries

(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 Peter to deliver his packages (y-intercept). Approximately how much did his delivery time decrease per day (slope)? Complete sentences

The answer is 560

Step-by-step explanation:

I just had this on a exam and answered 560 and it was correct.

d

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.

the answer is:

mean: 6

mad: 2.14
