Answer:
Slope of 1 with a y-intercept of 2
Step-by-step explanation:
Do you mean subtract two each day? If so...
4x3=12 and 12 divided by 2 is 6 so it would take six days to reach zero
or
you could manually subtract two from 6 each days as in 12-2=10 (1 day), 10-2=8 (2 days), and so on...
(s + 3t) * (2s - 2t) = 2s^2 - 2st + 6ts - 6t^2
