The line through the points (h, 3) and (...

The line through the points (h, 3) and (4, 1) intersects the line `7x-9y-19=0`at right angle. Find the value of h.

Text Solution

Verified by Experts

Condition for bisection of two lines perpendicularly is m₁m₂=-1

so the slope of a line with 2 given points is (y₂=y₁)/(x₂-x₁)

given points are (x₁,y₁)=(h,3) , (x₂,y2)=(4,1)

Now,put values in above formula of slope
