Question

What is the slope of the line passing through the points (- 2, 1 ) and ( 6, - 1)? *

A 2
B - 4
C - ¼
D ½
​

Answer 1

C. - ¼

Explanation:

1) if A(-2;1) and B(6;-1), then the required slope can be calculated according to the formula:

`s =(Y_A-Y_B)/(X_A-X_B);`

2) after the substitution the slope is:

`s= (1+1)/(-2-6)=-(1)/(4).`

3) answer: C. - ¼
