Does anyone understand??
DerKrebs [107]
Yes, so the Y intercept of the linear regression line is 250 ( it is on the y-axis at point [0,250]. You can also see that for every 2x the number on the y axis decreases by 50. This means that the slope is -25. Now put what we know into the equation for a line - y=mx+b 
y = -25x +250
