The correct answer is option A)
.
To find the equation that models the linear relationship in the given table, we can use the slope-intercept form
, where
is the slope and
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):
![\[m = \frac{\text{change in } y}{\text{change in } x} = (-5 - 10)/(1 - (-4)) = (-15)/(5) = -3.\]](https://img.qammunity.org/2021/formulas/mathematics/middle-school/ukghasclamo78rsdqlcixroa4vp19gygoc.png)
Now that we have the slope
, we can choose the correct equation from the options. Since the slope is negative, the correct equation should have a negative coefficient for
.
Comparing the options, the correct equation is
. To find
, we can use one of the points from the table, for example, (-4, 10):
![\[10 = -3(-4) + b \implies 10 = 12 + b \implies b = -2.\]](https://img.qammunity.org/2021/formulas/mathematics/middle-school/9fr4aigvx9hcxwva0u100mibiewkhuvyvn.png)
Therefore, the equation that models the linear relationship in the table is
, which corresponds to option A.
