The blue line of best fit for boys intersects the vertical axis at 20 inches and the point (12.5, 25). Which equation best describes the boy's line of best fit?

Reiny,
Is the relation supposed to be linear?
If so, then you have two ordered pairs,
(0,20) and (12.5 , 25)
Find the equation of that line using your usual method.
