Step-by-step explanation:
Photomath is a good one. So is KhanAcademy, but I don't know if they have an app version of the website.

Hope this helps! (:

Jenny does, she bakes 12 for every x and dan bakes 10 for every x.
So in conclusion jenny bakes more cookies per batch
For this case we have that by definition, the equation of the line of the slope-intersection form is given by:
![y = mx + b](https://tex.z-dn.net/?f=y%20%3D%20mx%20%2B%20b)
Where:
m: It is the slope of the line
b: It is the cut-off point with the y axis.
According to the data of the statement we have the following points:
![(x_ {1}, y_ {1}): (- 9, -9)\\(x_ {2}, y_ {2}): (- 6,0)](https://tex.z-dn.net/?f=%28x_%20%7B1%7D%2C%20y_%20%7B1%7D%29%3A%20%28-%209%2C%20-9%29%5C%5C%28x_%20%7B2%7D%2C%20y_%20%7B2%7D%29%3A%20%28-%206%2C0%29)
We found the slope:
![m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}} = \frac {0 - (- 9)} {- 6 - (- 9)} = \frac { 9} {- 6 + 9} = \frac {9} {3} = 3](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%20%7By_%20%7B2%7D%20-y_%20%7B1%7D%7D%20%7Bx_%20%7B2%7D%20-x_%20%7B1%7D%7D%20%3D%20%5Cfrac%20%7B0%20-%20%28-%209%29%7D%20%7B-%206%20-%20%28-%209%29%7D%20%3D%20%5Cfrac%20%7B%209%7D%20%7B-%206%20%2B%209%7D%20%3D%20%5Cfrac%20%7B9%7D%20%7B3%7D%20%3D%203)
Thus, the equation is of the form:
![y = 3x + b](https://tex.z-dn.net/?f=y%20%3D%203x%20%2B%20b)
We substitute one of the points and find b:
![0 = 3 (-6) + b\\0 = -18 + b\\b = 18](https://tex.z-dn.net/?f=0%20%3D%203%20%28-6%29%20%2B%20b%5C%5C0%20%3D%20-18%20%2B%20b%5C%5Cb%20%3D%2018)
Finally, the equation is:
![y = 3x + 18](https://tex.z-dn.net/?f=y%20%3D%203x%20%2B%2018)
Answer:
![y = 3x + 18](https://tex.z-dn.net/?f=y%20%3D%203x%20%2B%2018)
