A horn blows under water. A diver is about 9,000 feet away from the horn. About how many seconds does it take the diver to hear the sound of the horn?

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)

x = 12

y = 1

for the points!
