y 0 5 10 15
What is the constant of proportionality, k?

Enter your answer as a simplified fraction in the box.

k =

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
