Find the Minimum and Maximum Values of the Objective Function $z = 3 x + 4 y$

Find the minimum and maximum values of the objective function and where they occur, subject to the indicated constraints. Objective function: $z = 3 x + 4 y$ Constraints: $$\left\{ \begin{array} { l } y \geq 0 \\x - y \geq - 2 \\2 x + 3 y \geq 6 \\5 x + 2 y \leq 25\end{array} \right.$$

A) $\text { minimum } = 0 \text { at } ( 0,0 ) ; \text { maximum } = 29 \text { at } ( 3,5 )$
B) $\text { minimum } = 9 \text { at } ( 3,0 ) ; \text { maximum } = 15 \text { at } ( 5,0 )$
C) $\text { minimum } = 8 \text { at } ( 0,2 ) ; \text { maximum } = 27 \text { at } ( 3,5 )$
D) $\text { minimum } = - 11 \text { at } ( 3,5 ) ; \text { maximum } = 15 \text { at } ( 5,0 )$
E) $\text { minimum } = 8 \text { at } ( 0,2 ) ; \text { maximum } = 29 \text { at } ( 3,5 )$
