The temperature is 0 degrees at midnight and dropping 3 degrees per hour. The temperature is 9 degrees at a certain time. Find two equations that could represent the situation from the list of equations.
v=−16+6v = − 16 + 6

-3v=9−3v=9− 3 v = 9

v=9+3v=9+3v = 9 + 3

-4\cdot3=v−4⋅3=v− 4 ⋅ 3 = v

v=-\frac{1}{3}\cdot9v=−

⋅9v = − 1 3 ⋅ 9
