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.
(2,4), (4,7), (5,12)
The slope of the best fit line is 2.5. Find the y-intercept of this line.

Lets coordinate of y intercept are (0,y)
Since (0,y) is aslo on the line, find slope by using points (2,4) and (0,y)
m = y2-y1/x2-x1
2.5 = y-4 / 0-2
-5 = y-4
y = -5 +4
y = -1
