Answer:
N = (7/2)t +20
Step-by-step explanation:
In terms of years since 2010, the two given points are ...
(t, N) = (4, 34) and (6, 41)
Using the 2-point form of the equation for a line, we get ...
N = (n2 -n1)/(t2 -t1)(t -t1) +n1
N = (41 -34)/(6 -4)(t -6) +34 . . . . filling in the given points
N = 7/2(t -4) +34 . . . . simplifying a bit
N = (7/2)t +20 . . . your linear model
