Answer:
Nope!
Step-by-step explanation:
It's linear, because it has a continuous pattern. Look!
x values: 6, 7, 8, 9
y values: 4, 2, 0, -2
X values: We add 1 each time
Y values: We subtract 2 each time
I hope it helps!

Answer:
y= 1/4 (x -8)
Step-by-step explanation:
x -4y= 20
-4y= -x + 20
y= 1/4 × -5
y - y1 = m (x - x1)
y - 0 = 1/4 (x -8)
y= 1/4 (x -8)
You would beee to do 20/0.8 which would give you 25 water stations in total.
Hope that helped
