Answer :

To determine which relationship has a zero slope, we need to analyze the given tables of [tex]\( x \)[/tex] and [tex]\( y \)[/tex] values.

A relationship has a zero slope if the [tex]\( y \)[/tex]-values are constant, meaning they do not change regardless of the [tex]\( x \)[/tex]-values.

Let's examine the first table:
[tex]\[ \begin{array}{|c|c|} \hline x & y \\ \hline -3 & 2 \\ \hline -1 & 2 \\ \hline 1 & 2 \\ \hline 3 & 2 \\ \hline \end{array} \][/tex]

In this table, the [tex]\( y \)[/tex]-values are all 2. Since the [tex]\( y \)[/tex]-values do not change (they are constant), this relationship has a zero slope.

Now, let's examine the second table:
[tex]\[ \begin{array}{|c|c|} \hline x & y \\ \hline -3 & 3 \\ \hline -1 & 1 \\ \hline 1 & -1 \\ \hline 3 & -3 \\ \hline \end{array} \][/tex]

In this table, the [tex]\( y \)[/tex]-values are 3, 1, -1, and -3. Since the [tex]\( y \)[/tex]-values are changing and are not constant, this relationship does not have a zero slope.

Therefore, based on our examination:
- The first relationship ([tex]\( x \)[/tex] and [tex]\( y \)[/tex] pairs from the first table) has a zero slope.
- The second relationship ([tex]\( x \)[/tex] and [tex]\( y \)[/tex] pairs from the second table) does not have a zero slope.

Thus, the relationship with the zero slope is the first one.
