Question

If the foot of the perpendicular form the origin to a straight line is at the point (3, -4).

Answer 1

Slope of the line joining (0,0)and (3,-4)is

m=(-4-0)/(3-0)=-4/3.The required line is perpendicular to the line joining points. Hence the

Slope of required line is =3/4

Equation of required line is (y+4)=3/4(x-3)

4y+16=3x-9

3x-4y-25=0
