Answer
"... $x$ by $\underline2$ and $y$ by $\underline3$."
$(-2, \frac{1}{2})$
$(-1, 0)$
$(0, \frac{1}{2})$
$(1, 1)$
$(2, \frac{3}{2})$
See the image below.
Work Step by Step
The form of point coordinates is $(x, y)$, so $(2 ,3)$ means that $x=2$ and $y=3$
"... $x$ by $\underline2$ and $y$ by $\underline3$."
$2y=x+1$
Simplify for easier calculation:
$y=\frac{x+1}{2}$
$x=-2$
$y=\frac{-2+1}{2}=-\frac{1}{2}$
$(-2, \frac{1}{2})$
$x=-1$
$y=\frac{-1+1}{2}=\frac{0}{2}=0$
$(-1, 0)$
$x=0$
$y=\frac{0+1}{2}=\frac{1}{2}$
$(0, \frac{1}{2})$
$x=1$
$y=\frac{1+1}{2}=\frac{2}{2}=1$
$(1, 1)$
$x=2$
$y=\frac{2+1}{2}=\frac{3}{2}$
$(2, \frac{3}{2})$
