Which of the following is the equation for the graph shown? graph of an ellipse on a coordinate plane going through 12 comma 0, negative 12 comma zero, approximately 0 comma 10, and approximately 0 comma negative 10 with points inside ellipse at negative 7 comma 0 and 7 comma 0, and lines x equals 144 sevenths and x equals negative 144 sevenths

x squared over 144 plus y squared over 95 equals 1
x squared over 144 minus y squared over 95 equals 1
x squared over 95 plus y squared over 144 equals 1
x squared over 95 minus y squared over 144 equals 1
