What is the point slope form of a line, and why would you want to use it

Like other forms like slope intercept and standard form, point-slope form can be used as a preference. The point-slope equation already reveals one point and the slope of a line. Using this information, lines can be graphed quite easily.

42

step-by-step explanation:

256/6=42

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
