x1 y1 x2 y2
-1 -7 -8 -2

The general equation of the line when co-ordinates of two points are given is

%28y-%09y1%29%2F%28%09y1-y2%29+=+%28x-x1%29%2F%28x1-x2%29




%28y-%097++++++%09%29%2F%28%09-5++++++%09%29=%28x%2B%091++++++%09%29+%2F%28%097++++++%09%29

+%097++++++%09%28y-%097++++++%09%29+=%09-5++++++%09%28x-%09-1++++++%09%29

7 y- 49 = -5 x 5

7 y= -5 x+ 54
/ 7
1 y= - 5/ 7 x+ 54/ 7
