[填空题]
The coordinates of point K are (−2,−3) and the coordinates o pwbj**j5v5b*x3h8 ddvuk do ii5f;y 3f point N are (8,6,rn .yjs7sk6u ). M is the midpoint o7s 6k,rju.s ynf [KN].
1.Find the coordinates of M.
$L_1$​ is the line which passes through K and N. (a,b) a=   b=  
2.Find the gradient of $L_1$.
A new line, $L_2$​, is perpendicular to $L_1$ and passes through M. $L_1$ =   
3.(1)Write down the gradient of $L_2$​.$L_2$ =   
(2)Write down the equation of $L_2$ in the form y=mx+c. m =    c =
