F(x) = 2x + 1 and y = 2x + 1 are the same function written in different notation True or False?

The verbal translation for the difference of m and 7 increased by 15

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.
