Answer
The graph is shown below.
Work Step by Step
The inequality is
$x-y\lt5$
Step 1:- Replace the inequality symbol with $=$ and graph the linear equation.
$x-y=5$
Plug $y=0$ for the $x−$intercept.
$\Rightarrow x-0=5$
$\Rightarrow x=5$
The $x−$intercept is $5$, so the line passes through $A=(5,0)$.
Plug $x=0$ for the $y−$intercept.
$\Rightarrow 0-y=5$
Simplify.
$\Rightarrow -y=5$
Multiply both sides by $-1$.
$\Rightarrow -1(-y)=-1(5)$
Simplify.
$\Rightarrow y=-5$
The $y−$intercept is $-5$, so the line passes through $B=(0,-5)$.
Draw a straight line through these intercept points.
Step 2:- Choose a test point and plug into the inequality.
Let the test point $C=(0,0)$.
Plug the test point into inequality.
$\Rightarrow 0-0\lt5$
Simplify.
$\Rightarrow 0\lt5$
The statement is correct.
The solution set contains the test point.
Hence, the upper part of the line is the solution set.
