Y = mx + b
-3 = 1/2(-2) + b
-3 = -1 + b
b = -2
equation
y = 1/2x - 2
standard form
1/2x - y = 2
or
x - 2y = 4
This is invisible math but a whole bumber cant be converted to a decimal because if you were to see the whoole thing it would be 400.0
Answer:
After 5 hours, the amount of bacteria increased: 7800-6000=1800
After 1 hours, the amount of bacteria increased: 1800/5=360
After 18 hours, the amount of bacteria increased: 360*18 = 6480
=> Total amount of bacteria after 13 hours: 6000+6480 =12480
