Question

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

Answer 1

`\displaystyle -(15)/(4)`

Explanation:

Slope formula: ⇒
`\displaystyle (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((-7)-8)/(7-3)=(-15)/(4)=-(15)/(4)`

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

Hope this helps!
