A data set consists of the following data points: (2, 4), (4, 7), (5, 12) The slope of the best-fit line is 2.5. Find the y-intercept of this line.

need a graph paper to draw it

OpenStudy (imstuck):

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! : )
