Find the slope of the line that passes through (72, 60) and (73, -5).

-65

Step-by-step explanation:

We can use the slope formula

m= (y2-y1)/(x2-x1)

   = (-5-60)/(73-72)

   = -65/1

  = -65

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
