Answer
$\bf{Equations}$, $\bf{y=x+1}$,and $\bf{Test}$
Work Step by Step
To graph an inequality , firstly we need to draw a graph for the corresponding $\bf{Equations}$ , thus in order to draw the graph for inequality $y\leq x+1$, firstly we will draw the graph for the equation for $\bf{y=x+1}$. To decide the position or side of the inequality equation we will take the help of and $\bf{Test}$ points
Hence our answers are: $\bf{Equations}$, $\bf{y=x+1}$,and $\bf{Test}$
