Answer:

The expression of the ellipse is:
(x^2)/(4) + y^2 = 1

Explanation:

The equation of a ellipse can be written by the following expression:


(x^2)/(a^2) + (y^2)/(b^2) = 1

Where 2a is the length of the major axis and 2b is the length of the minor axi. Since we were given the length of the minor vertex, then:


2b = 2\\b = 1

The length of the major axis is the distance between the two vertices.


2a = √([2 - (-2)]^2)\\2a = √((2 + 2)^2)\\2a = √(4^2)\\2a = 4\\a = 2

Therefore the expression of the ellipse is:


(x^2)/(2^2) + (y^2)/(1^2) = 1\\\\(x^2)/(4) + y^2 = 1
