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

Answer:

C. - ¼

Step-by-step explanation:

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

$s =\frac{Y_A-Y_B}{X_A-X_B};$

2) after the substitution the slope is:

$s= \frac{1+1}{-2-6}=-\frac{1}{4}.$

3) answer: C. - ¼
