The equation of a line*0z;(jw5fz 6c4:il d*5 gfnd mttyjzbocmk6o 8p 49jw $L_1$​ is 2x+3y=−5.
1.Find the gradient of $L_1$​.
A second line, $L_2$, is perpendicular to $L_1$​. $mL_1$ =   
2.Find the gradient of $L_2$​.
The point P(4,0)(4,0) lies on $L_2$. $mL_1$ =   
3.Find the equation of $L_2$, giving your answer in the form ax+by+d=0, where a,b,d∈Z. a =    b =    d =   
The point Q is the intersection of $L_1$​ and $L_2$.
