Answer:
4 Minutes = 240 seconds = 6*40 seconds
30*(1/2)^6 = 30*1/64 = 30/64 = 15/32 = 0.5
4 minutes later there is approx. 0 to 1 bacteria alive.
The slope of the equation would be 7/3 since the original slope was -3/7. We already know y int (b) so the eqn is
y = 7/3x + 2
It is 2(3x+4) because you distribute the 2
