Which of the following is the equation for the graph shown?

graph of horizontal hyperbola on a coordinate plane going through 4 comma 0 and negative 4 comma 0 with points at 6 and 4 tenths comma 0 and negative 6 and 4 tenths comma 0, lines at x equals 2 and one half and x equals negative 2 and 49 hundredths

x squared over 25 minus y squared over 16 equals 1
x squared over 16 minus y squared over 25 equals 1
y squared over 16 minus x squared over 25 equals 1
y squared over 25 minus x squared over 16 equals 1
