Answer:
The slope of the line is -2
Step-by-step explanation:
<em>The rule of the slope of a line is</em>:
, where
and
are two points on the line
<em>Let us find the slope using the rule above</em>
∵ The line passes through points (3, -7) and (-1 , 1)
∴
= 3 and
= -1
∴
= -7 and
= 1
<em>Substitute these values in the rule above to find m</em>
∴ 
∴ The slope of the line that passes through the given points is -2
