Answer 5 and 6 please

The parabola opens: y=√x-4 (principal square root) up down right left

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.

Before simplifying, how many terms are there in the expression 2x - 5y + 3 + x?
