During the spring and summer, a concession stand at a community little league baseball game field sells soft drinks and other refreshments. to prepare for the season, the concession owner refers to the previous year’s files, in which he had recorded the daily soft drinks sales (in gallons) and the average daily temperature (in degrees fahrenheit). using the coordinates of the two points (84,80) and (74,65), determine the slope of the line of best fit.

Is there a direction u in which the rate of change of f(x,y)equals=x squared minus 3 xy plus 4 y squaredx2−3xy+4y2 at p(1,2) equals 14? give reasons for your answer. choose the correct answer below. a. no. the given rate of change is smaller than the minimum rate of change. b. no. the given rate of change is larger than the maximum rate of change. c. yes. the given rate of change is larger than the minimum rate of change and smaller than the maximum rate of change.
