It should be -3 I hope this helps
Answer:
20 gallons
Step-by-step explanation:
If 4 big water bottles can hold 8 gallons then just multiply 10x2 because that is double the amount.
(3,2),(-9,6)
slope = (6 - 2) / (-9 - 3) = -4/12 = -1/3
y = mx + b
slope(m) = -1/3
use either of ur points...(3,2)....x = 3 and y = 2
now we sub into the formula and find b, the y int
2 = -1/3(3) + b
2 = -1 + b
2 + 1 = b
3 = b
so ur equation is : y = -1/3x + 3 <==
