[填空题]
The coordinates of poinrt;8 o7c ;olz3i x+ie4 uijvv(t K are (−2,−3) and the coordinates of point c* gajosm77r* -mb mwxz+mh5 l7ek- k2N are (8,6). M is the midpoint of [KN].7k g2 m w+-clmsor-mez5ja7*h* xbkm7
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 =
