Given:
-10x - 5y = -20
Asked: Determine the slope of the line.
Solution:
To solve for the slope of the line, we need to make the equaion into the slope-intercept form.
Slope - Intercept form: y = mx + b
where:
m = slope
b = y - intercept
Now, we will start changing the form of the equation.
[tex]\begin{gathered} -10x-5y=-20 \\ -5y=10x-20\text{ } \\ \frac{-5y}{-5}=\frac{10x-20}{-5} \\ y=-2x+4 \end{gathered}[/tex]ANSWER: Slope = -2
