Kimmy is doing a science experiment where she studies how quickly amoebas how in a sample. She counts the amoebas several times during the day. The graph shows her data.

A= 1500t

1) Considering that time is the independent variable, and the number of Amoebas depends on the time, let's pick two points so that we can find the slope.

(2, 3,000) (3.5, 5250)

2) Now let's find the linear coefficient, the y-intercept of this. Picking one point (2, 3000)

y=mx +b

3000=1500(2)+b

3000= 3000 +b

b=0

3) Hence, we can notice that this function is proportional and can be written as

A= 1500t
