Estimate the equation for the regression line. Using the equation, find the residual of the regression line corresponding to the point (x = 105, y = 45)

x	138	116	105	88	66	32	26
y	23	8	45	69	86	112	131

(Do not round the intermediate values. Round your answers to 3 decimal places, e.g. 15.253. Enter negative amounts using either a negative sign preceding the number e.g. -15.253 or parentheses e.g. (15.253).)
