<h2>Answer:</h2>
First, we must determine <u><em>b</em></u> using <u><em>slope-intercept form*</em></u>, the given point, and the given slope.
Second, we need to set up the equation of the line in slope-intercept form.
Third, we convert the above equation to <em>STANDARD FORM**</em>.
We now have our equation:
*Slope-intercept form: <em>y = mx + b</em>
**Standard form: <em>ax + by = c</em>
Given:
The line passes through the points (8,-4) and (6,2).
To find:
The slope of the line.
Solution:
If a line passes though two points , then the slope of the line is
The line passes through the points (8,-4) and (6,2). So, its slope is
Therefore, the slope of the line is -3.
