Answer
The solution graph on the left is for "a" and for the right is "b"
Work Step by Step
Graph the lines that correspond to these inequalities and then shade the appropriate regions.
For a)
${2x+y\leq8, x-y\geq-2, x+2y\geq4}$ => ${y\leq8-2x,
y\leq2+x, y\geq(4+x)/2}$
For b)
${x^2 +y\leq5, y\geq2x+5 }$ => ${y\leq5-x^2 , y\geq2x+5}$
