Explanation:
Product of the slopes of two lines perpendicular to each other is
Writing the equation of given line
Hence slope of this line is
As such we have
or
Hence, slope of desired line is
we can have equation of desired line using point slope form of equation i.e.
or
or
or
graph{(3x+4y-12)(4x-3y-25)=0 [-6.21, 13.79, -3.32, 6.68]}
