Find the missing value so that the two points have a slope of -2 (1,y)and (6,-5)

im sorry this question doesnt make sese you cant have a slope represented by points on a graph

( such as (6,-5)

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
