Question

Find the slope of the line passing throught the points (3,8) and (7,-7)

Answer 1

Answer:

$\displaystyle -\frac{15}{4}$

Step-by-step explanation:

Slope formula: ⇒ $\displaystyle \frac{y_2-y_1}{x_2-x_1}$

$\displaystyle y_2=(-7)\\\displaystyle y_1=8\\\displaystyle x_2=7\\\displaystyle x_1=3$

$\displaystyle\frac{(-7)-8}{7-3}=\frac{-15}{4}=-\frac{15}{4}$

Therefore, the slope is -15/4, and the correct answer is -15/4.

Hope this helps!
