A bacterial colony started with 3,400 live cells. As part of an experiment, the colony is exposed to radiation, which kills the cells at a rate of 70 cells per second. 1. Find an equation that expresses the number of cells left living in the bacterial colony in terms of the number of seconds the colony has been exposed to radiation, 2. What is the y-intercept? Interpret it. y-intercept (z, y) = If the bacterial colony is exposed to radiation for seconds (that is, if the bacterial colony isn't exposed to radiation), there will be living cells in the colony 3. What is the slope? Interpret it. Slope: The line has a(n) [Select an answerv] direction, going from left to right. The shorter the bacterial colony is exposed to radiation, the greater the number of cells left alive in the colony The shorter the bacterial colony is exposed to radiation, the fewer the number of cells left alive in the colony. The longer the bacterial colony is exposed to radiation, the greater the number of cells left alive in the colony. The longer the bacterial colony is exposed to radiation, the fewer the number of cells left alive in the colony 4. If the bacterial colony is exposed to radiation for 8.8 seconds, how many cells would be left alive in the colony
