QR is located at Q(-5,-8) and R(-1,3). Which pair of points would form a segment congruent to QR?

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
