Answer
See the graph below:
Work Step by Step
We can see that at point $x=0$, the graph passes through $y=-1$.
We see that there is no $x$ variable in the first function.
Thus, the point is $\left( 0,-1 \right)$.
Now, at point $x=0.1$ , the graph passes through the following y-coordinate:
$\begin{align}
& y=2x+1 \\
& =2\left( 0.1 \right)+1 \\
& =0.2+1 \\
& =1.2
\end{align}$
Thus, the point is $\left( 0.1,1.2 \right)$.
And, at point $x=1$, the graph passes through the following y-coordinate:
$\begin{align}
& y=2x+1 \\
& =2\left( 1 \right)+1 \\
& =3
\end{align}$
Thus, the point is $\left( 1,3 \right)$.
