To determine the slope of a line is best to write the equation on the slope-intercept form.

The general structure of that form is


y=mx+b

Where

m is the slope

b is the y-coordinate of the y-intercept

Then to determine the slope of the given equation you have to write it in terms of y


2000=20x+10y

Pass the x-term to the other side


2000-20x=10y

Divide both sides by 10


\begin{gathered} (2000)/(10)-(20)/(10)x=(10)/(10)y \\ 200-2x=y \\ y=\text{-}2x+200 \end{gathered}

From this equation, we can determine that the slope corresponds to the coefficient that multiplies the x-term


y=-2x+200

The slope is m=-2
