In order to determine the value of "y" at the data point of (6,y), we need to use the slope of the line that describes the water level rise in the wading pool. The slope of a line describes how much the line rises or falls for a given horizontal distance. In this case, we know that the water level rises 16 cm every 3 minutes, so the slope of the line would be 16 cm / 3 minutes = 5.33 cm/minute. This means that for every minute that passes, the water level in the wading pool will rise by 5.33 cm. Therefore, if we know that the water level rose by 6 minutes, we can calculate the value of "y" by multiplying the slope by the time in minutes that the water level rose: y = 5.33 cm/minute * 6 minutes = 32 cm. This means that the water level in the wading pool at the data point of (6,y) is 32 cm.
