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.

Which ordered pair is a solution to the system of linear equations? 2x + 3y= 6 –3x + 5y = 10

Find the constant of variation for the relation and use it to write an equation for the statement. then solve the equation.
