1. Locus

$\textup{Consider hyperbola S::xy+7x+5y=0.}$

$\textup{If an ellipse touches the asymptotes of the curve S=0,}$

$\textup{then the eccentricity of locus of centre of the ellipse is??}$

sorry by mistake i posted in the rong forum...plzz move it to the correct one

Sorry, but the text of this question doesn't make sense to me: The asymptotes of the hyperbola are the straight lines with the equations y = -5
and x = -7.

You have to specify the form of the ellipse in question (ratio of the axes, geometric properties of the center, etc). Otherwise I can't help you.
