Question

A fish is swimming at a constant rate toward the ocean floor. The equation y = -3x - 7 can be used to represent this situation, where y is the depth of the fish in meters below sea level and x is the number of seconds the fish has been swimming.

Answer 1

Answer: x= -3/7

Step-by-step explanation: If trying to find when the fish will hit the floor you know that the floor is y=0 on a graph, so you can sub in 0 for y and solve for x and that will give you the seconds the fish will swim until hitting the bottom.
