The linear function E(t) that fits the data is?????

E(t)=?+?
E(14)=?

Answer 1

i will pass this one.

Answer 2

lol thanks

Answer 3

haha, i always leave this blank

Answer 4

lol me too

Answer 5

E(t)=33/50t+66.3
E(14)=75.54

Answer 6

how you got 33/50?

Answer 7

finding the slope between the two given points (1991,66.3) and (1996,69.6) is 3.3/5 or 33/50 the age at t=0 is 66.3

Answer 8

i was always confused about it's slope thanks man!
