When using the Simplex method to minimize 13x + 4y subject to the constraints
y ≥ -2x + 11
y ≤ -x + 10
y ≤ (-1/3)x + 6
y ≥ (-1/4)x + 4
x ≥ 0
y ≥ 0
What is the first step?
A. Graph the constraints
B. Add in the slack variables
C. Rewrite the constraints in standard form
D. Create the initial tableau
