find the equation of a straight line whose x-intercept and y-intercept are(adsbygoogle = window.adsbygoogle || []).push({}); aandbrespectively.If this line varies such that [tex]\frac{1}{a^2}[/tex] + [tex]\frac{1}{b^2}[/tex] = [tex]\frac{1}{c^2} [/tex]with c as a constant,show that the locus of the foot of the perpendicular from the origin to this line is the curve

[tex] X^2[/tex] +[tex] Y^2[/tex] = [tex]C^2 [/tex].

I want to ask what is meant by the phrase 'foot of the perpendicular from the origin to this line ' ?

I hope that somebody will help me to explain the meaning and thanks for anybody that spend some time on this question.
