Answer:
1
Option B is the right option.
Solution,
Let the points be A and B
A(2,7)---->(X1,y1)
B(-1,4)---->(x2,y2)
Now,
[tex]slope = \frac{y2 - y1}{x2 - x1} \\ \: \: \: \: \: = \frac{4 - 7}{ - 1 - 2} \\ \: \: \: \: \: = \frac{ - 3}{ - 3} \\ \: \: \: \: = 1[/tex]
Hope this helps..
Good luck on your assignment..
