Question

Write an equation of a line perpendicular to the line ax + by = c that passes through the point (-1,2).

Answer 1

Answer:

Step-by-step explanation:

line perpendicular to ax+by=c is

bx-ay=k, where k is a constant.

if it passes through (-1,2) then

b(-1)-a(2)=k

or k=b-2a

so reqd. eq . is bx-ay=b-2a
