Answer: The slope is -1/2.
Step-by-step explanation:
-To figure out the slope, you first need the slope formula:
[tex]m=\frac{rise}{run} =\frac{y2-y1}{x2-x1}[/tex]
-Set the two points to the equation:
[tex]m=\frac{52-62}{40-20}[/tex]
- Then you solve to get the slope:
[tex]m=\frac{52-62}{40-20} = -\frac{1}{2}[/tex]
-Result:
[tex]m =- \frac{1}{2}[/tex]
