Questions
A line perpendicular to the line segment joining the points and divides it in the ratio , the equation of the line is
a
x+y-10=0
b
x-y+4=0
c
x-y+2=0
d
x-y-2=0
detailed solution
Correct option is D
Slope of the given line is 7-33-7=-1 and the coordinates of the point which divides the given line segment in the ratio 1:3 is 1×3+3×74,1×7+3×34=(6,4)So equation of the line passing through the point (6, 4) and perpendicular to the given line isy−4=x−6 ⇒ x−y−2=0.Talk to our academic expert!
