The answer is - 2
Step-by-step explanation:
The slope of a line given two points can be found by using the formula
![m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\](/tpl/images/0793/5438/fc802.png)
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(3, β7) and (β1, 1)
The slope is
![m = \frac{1 - - 7}{ - 1 - 3} = \frac{1 + 7}{ - 4} = - \frac{8}{4} = - 2 \\](/tpl/images/0793/5438/8d90e.png)
We have the final answer as
- 2
