To find the right answer, first, we find the slope.

Let's use the slope formula, and the points (0,8) and (8,4).

[tex]m=\frac{y_2-y_1_{}}{x_2-x_1}[/tex]

Replacing the points, we have.

[tex]m=\frac{4-8}{8-0}=\frac{-4}{8}=-\frac{1}{2}=-0.5[/tex]

However, the Value is express in thousands of dollars, which means the slope is -500.

Observe that G is the only equation with the correct slope.

Therefore, G is the right answer.
