Answer:
The result is B) -15/2 .
Step-by-step explanation:
-To find the slope, you need the slope formula:
[tex]m = \frac{y_{2} - y_{1}}{ x_{2} - x_{1}}[/tex]
-Use those two points (5, 80) and (7, 65) for the formula:
[tex]m = \frac{65-80}{7-5}[/tex]
-Then, you solve that formula:
[tex]m = \frac{65-80}{7-5}[/tex]
[tex]m =- \frac{15}{2}[/tex]
So, the answer for the slope is [tex]-\frac{15}{2}[/tex] .
