Question

Solve the given inequalities graphically:

$2x+y$ $\ge$ $8,x+2y$$\ge$$10$

Answer 1

Blue line is $2x+y=8$ and red line is $x+2y=10$
Now according to question we have to look over the region which
$2x+y\ge 8andx+2y\ge 10$ they intersect at point $(2,4)$
So for $x>2$ region is above or on the line $x+2y=10$
and for $x<2$ region is above or on the line $2x+y=8$
