slope of any line containing this points is={4-(-3)}/(-1-2)
=7/-3
=-7/3
slope of any line parallel to this is also the same. hence the required answer is option is 'a'

slope = Y - y / X - x
= -3-4 / 2 - (-1)
= -7/3
so ans A.

Slope = rise/run, ={y(2)-y(1)}/ {x(2)-(x(1)}
={4-(-3)}/{(-1)-2}
=7/-3, or -7/3
Answer is a. -7/3
