[填空题]
The coordinates of p,ebo xs2xc 0l+oint A hanw 92lgbjm*k8f3/ y are (6,−3) and the coordinates of point B are (−2,−1)byf2nalmhgk/8 w9j 3* . $L_1$ is the line which passes through A and B.
1.Find the equation of $L_1$.
Point M is the midpoint of [AB]. The line $L_2$​ is perpendicular to $L_1$​and passes through M. y = ax+b a =    b =   
2.Find the equation of$L_2$. y = ax+b a =    b =
