Question

Write inequality shown by shaded region on graph. Line x+y=5

Answer 1

Given the line x+y=5, solving for y,

$\Rightarrow y=5-x$

Notice that, at x=5, the values of y in the shaded region are y=1,2,3,...>0

Therefore,

$\Rightarrow y\ge5-x$

The inequality whose solution is the shaded region is y>=5-x
