need a graph paper to draw it

The slope of the best-fit line corresponds perfectly with the points (2, 4) and (5, 12).  The slope corresponding to those points is 2.5 exactly.  I continue going to the left .5 and down 2 and I cross the y-axis at the origin, actually, (0, 0).  I hope that's right! : )
