Ataxi cab service charges it customers based on initials, fixed fee and a per-mile rate. the equation c=2.5m+5 models this situation, where c is the total cost of a ride and m is the number of miles traveled. identify the values of the slope and the y-intercept in this equation

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.
