Answer

Explanation:

Step1: Recall slope - formula

The point - slope form is $y - y_1=m(x - x_1)$, where $m$ is the slope. We have two points: $(0,80000)$ and $(10,50000)$. The slope formula is $m=\frac{y_2 - y_1}{x_2 - x_1}$.

Step2: Identify points

Let $(x_1,y_1)=(0,80000)$ and $(x_2,y_2)=(10,50000)$.

Step3: Calculate slope

$m=\frac{50000 - 80000}{10-0}=\frac{- 30000}{10}=-3000$.

Answer:

A. -3,000
