a parabola can be drawn given a focus of (4, -7)and a directrix of y=5. write the equation of the parabola in any form.

What is the value of x in the diagram below?

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 y varies directly as x2 and y=6 when x=6, find the constant of variation.
