first plot all points:
as you can see, there is no line that passes through all these points, they are not on same line; so, we can only find a best-fit line for a set of data
all we can do to turn this into a linear function  ,is to choose two given points which are somehow in the middle and find a slope  :
 ...use points (,) and ( , )
so far, your equation is 
you need y-intercept  , so use one point and plug and value in 
I will go with this one:(,)
and you have:
graph it and check if that line is the best fit for given points:
so, the line is a best-fit line for given set of points
