The correct answer is option A)
\(y = -3x - 2\).

To find the equation that models the linear relationship in the given table, we can use the slope-intercept form
\(y = mx + b\), where
\(m\) is the slope and
\(b\) is the y-intercept. We'll calculate the slope using two points from the table.

Let's use the points (-4, 10) and (1, -5):


\[m = \frac{\text{change in } y}{\text{change in } x} = (-5 - 10)/(1 - (-4)) = (-15)/(5) = -3.\]

Now that we have the slope
(\(m = -3\)), we can choose the correct equation from the options. Since the slope is negative, the correct equation should have a negative coefficient for
\(x\).

Comparing the options, the correct equation is
\(y = -3x + b\). To find
\(b\), we can use one of the points from the table, for example, (-4, 10):


\[10 = -3(-4) + b \implies 10 = 12 + b \implies b = -2.\]

Therefore, the equation that models the linear relationship in the table is
\(y = -3x - 2\), which corresponds to option A.

The question probable maybe:
