What is the rational expression of m in this equation? 1/m = 2/m+7

Which is a true statement comparing the graphs of x^2/6^2-y^2/8^2 = 1 and x^2/8^2-y^2/6^2 the foci of both graphs are the same points. the lengths of both transverse axes are the same. the directrices of = 1 are horizontal while the directrices of = 1 are vertical. the vertices of = 1 are on the y-axis while the vertices of = 1 are on the x-axis.

#1-20 state whether the angles are alternate interior, alternate exterior, vertical, or corresponding angles.

Does anyone know how to do geometryme with this problem
