Answer:
-1/3
Step-by-step explanation:
To find the slope, we can use the slope formula
m = ( y2-y1)/(x2-x1)
= ( 9-10)/(10-7)
= -1/3

The total mass, in kilograms, of the nails the carpenter bought is 3.9 kilogram
<h3><u>Solution:</u></h3>
Given that carpenter bought 750 nails
Each nail has a mass of
kilogram
To find: total mass, in kilograms of the nails bought
The total mass of the nails bought can be found out by multiplying number of nails bought by mass of each nail
Number of nails bought = 750
Mass of each nail =
kilogram
total mass of the nails bought = number of nails bought x mass of each nail
![\text {total mass of the nails bought }=750 \times 5.2 \times 10^{-3}](https://tex.z-dn.net/?f=%5Ctext%20%7Btotal%20mass%20of%20the%20nails%20bought%20%7D%3D750%20%5Ctimes%205.2%20%5Ctimes%2010%5E%7B-3%7D)
![\text {total mass of the nails bought }=3900 \times 10^{-3}=\frac{3900}{1000}=3.9](https://tex.z-dn.net/?f=%5Ctext%20%7Btotal%20mass%20of%20the%20nails%20bought%20%7D%3D3900%20%5Ctimes%2010%5E%7B-3%7D%3D%5Cfrac%7B3900%7D%7B1000%7D%3D3.9)
Thus the total mass of nails bought is 3.9 kilogram
