Plz help me! I’m not sure how to do these!

What is the point-slope equation of a line with slope -5 that contains the point (6,3)

What could explain what happened when the time was equal to 120 minutes

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.
