Answer 1

The "line of best fit" is the result of a linear regression computation. If you have done that, you already know its equation.

If you have "eye-balled" the line into place, then you have to figure out its equation from points you read on the graph. We take a couple of the points to be ... (2001, 1700) and (2010, 2450)

The line through these points will have the equation

... y = (2450 -1700)/(2010 -2001)(x -2001) +1700

... y = (250/3)(x -2001) +1700

Putting x=2013 into this equation, we get ...

... y = (250/3)(2013 -2001) +1700

... = (250/3)(12) +1700

... y = 2700

The population is predicted to be 2700 in 2013.

Had you drawn your graph with a vertical grid line at 2013, you could have read the number from the graph.
