Question

Determine the slope of the line represented by the equation: -10x - 5y = -20DO NOT USE 1 AS THE DENOMINATOR!

Answer 1

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.

`\begin{gathered} -10x-5y=-20 \\ -5y=10x-20\text{ } \\ (-5y)/(-5)=(10x-20)/(-5) \\ y=-2x+4 \end{gathered}`

ANSWER: Slope = -2
