Answer:
The numbers are missing, as well as the first part of the question. I looked for a similar question and found the attached data.
first you need to calculate the regression line equation, which in this case = 0.59343x + 2.01844
the slope coefficient = 0.59343
if the price of milk differs by $0.15, then the price of eggs will change by $0.15 x 0.59343 = $0.089 or $0.09
