Question: Concrete expands both horizontally and vertically over time. An article reports measurements of horizontal and vertical expansion (in units of parts per hundred thousand) made

Concrete expands both horizontally and vertically over time. An article reports measurements of horizontal and vertical expansion (in units of parts per hundred thousand) made at several locations on a bridge in Quebec City in Canada. The results are presented in the following table. Horizontal Vertical 43 55 5 80 18 58 24 66 32 57 10 69 21 63 Compute the least-squares line for predicting vertical expansion (y) from horizontal expansion (x). (Round the final answers to three decimal places.)
