Question

Find the slope of the line perpendicular to the line which passes through the pair of (-k,h)and(b,f)​.​

Answer 1

Answer:

the pair of (-k,h)and(b,f).

slope of this line = m1 = (f-h)/(b+k)

condition for perpendicular

m1.m2 = -1

(f-h)/(b+k).m2 = -1

m2 = -(f-h)/(b+k)

or

m2 = (h-f)/(b+k)
