Answer:
The answer is
The answer is option A
Step-by-step explanation:
The slope of a line given two points can be found by using the formula
[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\[/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
D(3,5) and F(-2,7)
We have
[tex]m = \frac{7 - 5}{ - 2 - 3} = \frac{2}{ - 5} = - \frac{2}{5} \\ [/tex]
We have the final answer as
[tex] - \frac{2}{5} \\ [/tex]
Hope this helps you
