Answer:
The slope is m=0
Explanation:But since the y-coordinates of the points are equal, we can find the slope easier than just by using above formula.
Explanation:But since the y-coordinates of the points are equal, we can find the slope easier than just by using above formula.If y-coordinates are equal and x-coordinates are not equal (as in our case), then the slope equals 00 (the line is horizontal).

Answer:
B. equivalent
Step-by-step explanation:
Our two equations are:
![y=-\frac{1}{3} x +\frac{2}{3}](https://tex.z-dn.net/?f=y%3D-%5Cfrac%7B1%7D%7B3%7D%20x%20%2B%5Cfrac%7B2%7D%7B3%7D)
![2x+6y=4](https://tex.z-dn.net/?f=2x%2B6y%3D4)
Let's use substitution and plug in the expression
for y in the second equation. That way, we're getting rid of a variable so we can solve for the other:
![2x+6y=4](https://tex.z-dn.net/?f=2x%2B6y%3D4)
![2x+6(-\frac{1}{3} x +\frac{2}{3})=4](https://tex.z-dn.net/?f=2x%2B6%28-%5Cfrac%7B1%7D%7B3%7D%20x%20%2B%5Cfrac%7B2%7D%7B3%7D%29%3D4)
![2x-2x+4=4](https://tex.z-dn.net/?f=2x-2x%2B4%3D4)
![4=4](https://tex.z-dn.net/?f=4%3D4)
![0=0](https://tex.z-dn.net/?f=0%3D0)
This means that there are an infinite number of solutions possible for this system - any x value will work. So, the answer is equivalent, because these two equations are essentially the same.
Depends how many friends she has. Whatever that number may be, divide it by both 30 and 45 to have the same number per friend. If you get a decimal or fraction then round down to the nearest whole number
Example: 10 friends
30/10= 3 so 3 snack bars
45/10=4.5 so 4 juice boxes
<span>(38 + 28) / 4 = 16,5. A. 16.5 bird feeders per hour. </span>
