Write an equation for the function that includes the points (1,4/5) and (2,2/3)

36x2 + 49y2 = 1,764 the foci are located at: (-√13, 0) and (√13,0) (0, -√13) and (0,√13) (-1, 0) and (1, 0)edit: the answer is (- the square root of 13, 0) and (the square root of 13, 0)

Yvaries directly as x. y =90 when x=6. find y when x=13
