It should be for 5 hours if $30 is what they started with
For this case we have that by definition, the equation in the form of slope-intersection is given by:
![y = mx + b](https://tex.z-dn.net/?f=y%20%3D%20mx%20%2B%20b)
Where
Substituting the given point:
and the cutoff point
we can find the slope,
We have:
![-4 = m * 2-2\\-4 = 2m-2\\-4 + 2 = 2m\\-2 = 2m](https://tex.z-dn.net/?f=-4%20%3D%20m%20%2A%202-2%5C%5C-4%20%3D%202m-2%5C%5C-4%20%2B%202%20%3D%202m%5C%5C-2%20%3D%202m)
![m =-\frac{2}{2}\\m = -1](https://tex.z-dn.net/?f=m%20%3D-%5Cfrac%7B2%7D%7B2%7D%5C%5Cm%20%3D%20-1)
Thus, the equation is given by:
![y = -x-2](https://tex.z-dn.net/?f=y%20%3D%20-x-2)
Answer:
![y = -x-2](https://tex.z-dn.net/?f=y%20%3D%20-x-2)

Step-by-step explanation:
4unity to the left
3unity down
Answer:
$0.45
Step-by-step explanation:
1 tin of beans-> $1.55÷3=$0.31
3 tins of beans-> $0.31×3=$0.93
4 tins of tomatoes-> $2.73-$0.93=$1.80
1 tin of tomatoes->$1.80÷4=$0.45
