On a coordinate plane, 2 straight lines are shown. the first solid line is horizontal at y = negative 1. everything above the line is shaded. the second dashed line has a negative slope and goes through (negative 2, 1) and (0, 0). everything below the line is shaded. a system of inequalities can be used to determine the depth of a toy, in meters, in a pool depending on the time, in seconds, since it was dropped. which constraint could be part of the scenario?
a. the pool is 1 meter deep.
b. the pool is 2 meters deep.
c. the toy falls at a rate of at least a -1/2 meter per second.
d. the toy sinks at a rate of no more than a -1/2 meter per second.
