Find an equation for the parabola with focus (2,6) and directrix y=2

The length of a rectangular piece of land is 92 yards more than three times its width. the perimeter is 760 yards. find its dimensions.

Which of the points a(6, 2), b(0, 0), c(3, 2), d(−12, 8), e(−12, −8) belong to the graph of direct variation y= 2/3 x?

Assume that y varies inversely with x. if y=1.6 when x=0.5 find x when y=3.2
