Can you please help on this question so is says the black line is the graph of y=x which of these equations could represent the blue line y=0.001x y=2x y=1/2x or y=-x

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.

Write an expression that has three terms and simplifies to 4x - 7. identify the coefficient(s) and constant(s) in your expression

If a || b and b | y, then ? a) x || y. b) x | a. c) a | y. d) a || y.
