**Steve**, Friday, July 11, 2014 at 4:02pmsince there's y^2 but no x^2, it's a parabola, opening to the right:

5x = 4y^2 - 3y - 7

x = 4/5 y^2 - 3/5 y - 7/5

x = 4/5 (y^2 - 3/4 y) - 7/5

x = 4/5 (y^2 - 3/4 y + (3/8)^2) - 7/5 - 4/5 * (3/8)^2

x = 4/5 (y - 3/8)^2 - 121/80

so the vertex is at (-121/80,3/8)
