What is the slope of the line that passes through (3, −7) and (−1, 1)? Undefined
0
−2
2

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(3, −7) and (−1, 1)

The slope is

We have the final answer as

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
