Pls help im honestly brain dead

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.

If sec theta = 5/3 and the terminal point determined by theta is in quadrant 4, then

X2 + y 2 = 36 x + y = 6 solve the system of equations.
