Answer
The table, equation, and graph are shown below.
Work Step by Step
Table: Figure 1 below is a table showing the relationship between the $x-$ and $y-$ coordinates of the given points.
Equation: Let $y$ be the $y$-coordinate of the given points and $x$ be the $x$-coordinate. Using the given point $(1,-4.5)$, the relationship between the $x$ and $y$ coordinates is
$$
y=-x-3.5
$$
Graph: Figure 2 below is a graph showing the relationship between the $x-$ and $y-$ coordinates of the given points.
