Which pairs of lines are perpendicular? y=3x-5y=3x−5 and y=3x+4y=3x+4

y=3x-5y=3x−5 and y=1/3x-5y=1/3x−5

y=3x-5y=3x−5 and y=-1/3x-5y=−1/3x−5

y=3x-5y=3x−5 and y=-3x-5y=−3x−5

(08.01)consider the following pair of equations: x + y = −2 y = 2x + 10 if the two equations are graphed, at what point do the lines representing the two equations intersect? (−4, 2) (4, 2) (−2, 4) (2, 4)

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.

I’m really confused and need your assist me with this question i’ve never been taught
