If you are given 2 coordinates and u need to find the equation of the line, then lets do the 2 point form.
(5,-6)(9,-1)
[tex]y-y_{1}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}(x- x_{1}) [/tex]
[tex]y+6=\frac{-1+6}{-9-5}(x-5)[/tex]
Multiply both sides by 13
[tex]-13y-78=5x-25[/tex]
0=5x+13y+53
The equation of the line is 5x+13y+53=0. Hope this helps =)
