is equivalent to <span>

That is in the form </span><span>

which is point slope form
In this case,
m = 1/2 is the slope
(x1,y1) = (7,-8) is the point the line goes through</span>
5 x + 3 y = 41 / * 3
3 x + 2 y = 26 / * ( - 5 )
-----------------------------
15 x + 9 y = 123
+
- 15 x - 10 y = - 130
---------------------------
- y = - 7 / * ( - 1 )
y = 7
