Line perpendicular to a given line is = 1/m
To find m, use m =y2-y1/x2-x1 formula
m = (8-(-3))/(-7-4)
m = 11/-11,
m = -1
Use y= mx+c to find equation of line
Plug in a pair of values,
-3= -1(4)+ c
c= 1
Thus, equation is:
y = -x+1
Equation of line perpendicular to this line is:
y= x+1

Answer:
y=-180/7
Step-by-step explanation:
7x-12y =180 --(i)
x=12 --(ii)
Substituting the value of from eqn (ii) in eqn (i), we get
7x-12y=180
7*12-12y=180
-12y=180/84
y=180/84*-12
y=-180/7
