Answer:
[tex]\displaystyle -\frac{15}{4}[/tex]
Step-by-step explanation:
Slope formula: ⇒ [tex]\displaystyle \frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\displaystyle y_2=(-7)\\\displaystyle y_1=8\\\displaystyle x_2=7\\\displaystyle x_1=3\\[/tex]
[tex]\displaystyle\frac{(-7)-8}{7-3}=\frac{-15}{4}=-\frac{15}{4}[/tex]
Therefore, the slope is -15/4, and the correct answer is -15/4.
Hope this helps!
